Rubber Materials
In order to obtain the longest possible lifetime for rubber seals it is essential to choose the right quality for the actual duty.
Consequently when choosing rubber quality, the characteristics of the different rubber types should be considered. All product
wetted rubber material are in conformity of FDA.

EPDM Rubber (Ethylene Propylene)

EPDM rubber is widely used within the food industry as it is resistant to most products used in this sector. Another advantage is that
it may be used to a recommend max. temperatures of 140°C (244°F). However, there is one essential limitation, EPDM is not
resistant to organic and non-organic oils and fats.

Actylonitrile Butadiene Rubber, NBR

NBR is the rubber type most frequently used for technical purposes. It is quite resistant to most hydrocarbons, e.g oil, grease and
fat. It is sufficiently resistant to diluted lye and nitric acid and may be used to a recommended max. 95°C (203°F). As NBR is
attacked by ozone it may not be exposed to ultraviolet rays and should thus consequently be stored so that this is avoided.

Silicone rubber, Q
The most significant quality of silicone rubber is that it can be applied from temperatures below -50°C (-58°F) to approx. + 180°C
(356°F) and still keep its elasticity. The chemical resistance is satisfactory to most products. However, undiluted lye and acids as well
as hot water and steam may destroy silicone rubber. The resistance to ozone is good.

Fluorine rubber, FPM

FPM is often used when other rubber types are unsuited, especially at high temperatures up to approx. 180°C (356°F). The chemical
resistance is good to most products, however hot water, steam, lye, acid and alcohol should be avoided. The resistance to ozone is
good.

Hydrogenated actylonitrileButadiene Rubber, HNBR

Mechanically strong and normally resistant to ozone and strong oxidizers, animal and vegetable fats, nonpolar solvents, oils and
lubricants, water and aqueous solutions. The recommend max. temperature is 130°C (266°F).
Perfluoroalkoxy polymer, PFA
PFA is very similar to PTFE, but opposite to those PFA is thermo plastic and has minimal porosity. PFA has a very high mechanical
strength which makes it a perfect choice when dealing with abbrasive products. The PFA seal offers longer service intervals. The
recommended max. temperature for the PFA seal is 90°C (194°F).

Product and chemical resistance of flexible rubber materials

The information below is intended as an aid in selecting the best rubber quality for an actual application. It is not possible to state
any general lifetime of rubber seals as many factors influence it: chemical attack, temperature, mechanical wear etc. Extreme
temperatures, even within the generally accepted limits, may worsen other kinds of attack and thus reduce the lifetime.

Ratings
1 = Unsuitable.

2 = Limited suitability.

3 = Normal suitability.

4 = High suitability.

- = Not recommended for other reasons.

The 5308/5309 Series Ball Valves are designed for use as
product valves in high-pressure, high-temperature applications
as well as applications that require the use of pigging systems.
They are ideal for use across the dairy, food, beverage, brewery
and many other industries.

Benefits
• Reliable and effective full-flow performance

• Compact, straightforward design

• Ideal for high-pressure, high-temperature applications or

applications that require the use of pigging systems

• Minimizes line turbulence and pressure drop

• Easy to inspect and maintain due to welded-end flange

screws that enable quick assembly and disassembly

Standard design
The Alfa Laval 5308/5309 Series Ball Valves consist of a
stainless steel valve body, two flanges, two PTFE valve seats,
ball, and a stem unit. The valve body houses a rotating ball,
which is sealed in the body with a PTFE seat that either partially
or fully encapsulates the ball. The valve is activated by a
stainless steel handle that opens and closes the valve through a
quarter turn. The stem and seal design eliminate the risk of
dislodging or blowing out the stem.

Butterfly valves

Introduction
The Alfa Laval LKB Butterfly Valve is a reliable, hygienic in-line
valve for routing low and medium-viscosity liquids in stainless
steel pipe systems due to its substantial opening area and low
flow resistance. The LKB is available with a standard handle with
spring-locking action for straightforward manual operation or
with a pneumatic actuator for pneumatic operation.

Application
This hygienic valve is designed for on-off duties with low to
medium-viscosity liquids in hygienic applications across the
dairy, food, beverage, brewery and many other industries.

Benefits
• Versatile, highly modular, hygienic design
• Reliable, cost-effective performance
• Easy to configure in either a manual version or a pneumatic
version

Standard design
The LKB Butterfly Valve consists of two valve body halves, valve
disc, and bushings for the disc stem and a seal ring. These
components are assembled by means of screws and nuts. The

feedback on the valve position (open or closed).
Working principle
The Alfa Laval LKB UltraPure Butterfly Valve is either controlled
remotely by means of an pneumatic actuator or manually by
means of a handle.

For pneumatic operation, an actuator converts axial piston

motion into a 90° rotation of the shaft. The actuator torque
increases as the valve disc comes into contact with the seal ring
of the butterfly valve to secure proper closing of the valve seat.
The actuator comes in three standard versions: normally closed
(NC); normally open (NO); and, air/air activated (A/A). Two
actuator sizes, ø 3.35" and ø 5.24", cover all valve sizes and are
available in two versions, LKLA and LKLA-T (T for mounting of
indication or control unit on the actuator).

Alfa Laval Unique Control
Butterfly valves

Introduction
The Alfa Laval Unique Control is a maintenance-free actuator
with integrated control unit for most of Alfa Laval LKB Butterfly
Valves. Reliable and straightforward, this automation solution
complements the range of Alfa Laval actuators and control
units, making it easy to upgrade existing installations. Highly
durable, this actuator has been tested to perform above one
million strokes and is compatible with all major programming
logic controller (PLC) systems.

Application
This intelligent, hygienic actuator is designed for superior flow
control in dairy, food, beverage, brewery, biotech,
pharmaceutical and many other industries.

Benefits
• A single, integrated automation solution for Alfa Laval LKB
Butterfly Valves
• Highly durable, reliable, all-in-one actuator
• Simplified auto setup for butterfly valve control
• Clearly visible 360° LED indication of valve operation
• Easy upgrade for manual and automated butterfly valves

Standard design
The Alfa Laval Unique Control actuator for butterfly valves is an
intelligent sensing and control unit engineered as a single,
integrated unit. It is available with a digital or AS-Interface. The
actuator comes with a matching bracket kit for mounting on
butterfly valves in sizes 1” - 4” or DN25 - DN100.

Working principle
The Alfa Laval Unique Control LKB actuator uses an air spring,
enabling operation at a significantly lower air pressure than using
a conventional mechanical spring. A single push of a button
enables the actuator to perform easy, onsite self-configuration
and calibration tasks according to the operating air pressure
provided. The actuator also monitors the operating air pressure
and will send alerts about issues that require attention in order
to prevent any malfunctions, ensuring more uptime.

Alfa Laval LKC Non-return Valve
Control/Check valves

Introduction
The Alfa Laval LKC Non-return Valve is a hygienic one-way
check valve for use in various processes across the hygienic
industries to prevent reverse flow. It is easy to install, ensuring
safety and high product quality. It is available in two versions: the
LKC-2 for vertical flow and the LKC-H for horizontal flow.

Application
The LKC Non-return Valve is widely used for single directional
product flow through hygienic process lines across the dairy,
food, beverage, brewery and many other industries.

Benefits
• Highly reliable, self-acting valve
• Easy to install
• Protects process equipment
• Prevents reverse flow

Standard design
The Alfa Laval LKC Non-return Valve consists of a valve body in
two parts, valve plug and spring, assembled by means of a
clamp ring and hygienically sealed with a special seal ring. A
guide disc with four legs ensure alignment of the spring-loaded
valve plug with an o-ring seal. The valve is available with weld
and clamp ends for ISO and DIN tubing connections.

Working principle
The Alfa Laval LKC Non-return Valve opens and closes
depending on the pressure. The spring acts on the valve plug
and keeps the valve closed until the force from the pressure in
the inlet exceeds the force of the spring. If a reverse flow should
occur, the spring force and the pressure from the outlet will keep
the valve closed. Required differential pressure for opening the
valve when fitted in a vertical pipe is approximately 0.87 PSI
(0.06 bar).

Alfa Laval LKUV-2 Air-relief Valve
Control/Check valves

Introduction
The Alfa Laval LKUV-2 is a reliable, self-acting air relief valve that
releases excess air from process pipelines, or pumps to prevent
cavitation and product loss, thereby preventing the negative
effects of air entrainment.

Vertically installed, it is ideal for use where the removal of air is

required to maintain design pressure conditions, such as at the
top of a pipeline, or pump inlet pipe on the suction side to
remove excess air before starting the pump.

Application
This self-acting relief valve is designed for air-venting duties in
hygienic applications across the dairy, food, beverage and many
other industries. It is typically used in Cleaning-in-Place return
line (CIP-R) applications.

Benefits
• Improved processing efficiency and product integrity
• Enhanced energy efficiency
• Protects pumps against the risk of cavitation
• Low total cost of ownership

Standard design
The LKUV-2 Air-relief Valve consists of a stainless-steel valve
body in two parts, seal ring and polypropylene ball. The lower
valve body has a welding stub. The valve body is assembled by
means of a clamp.

Working principle
The Alfa Laval LKUV-2 Air-relief Valve is an air-relief valve with a
free moving polypropylene ball, which is lighter than water. The
polypropylene ball alternates between two seats depending on
pressure conditions on the inlet.

When the pressure on the inlet increases, the ball is forced off
the lower valve seat and moves to the upper seat, thereby
closing the valve against the atmosphere. If air enters the
system, the pressure is reduced, thereby moving the ball away
from upper seat and venting excess air to the atmosphere. If
there is no pressure or vacuum in the system, the ball alternates
to lower position thereby closing the valve.

Alfa Laval 62-174/326 Air Blow Check Valve
Control/Check valves

Introduction
The Alfa Laval 62-174/326 Air Blow Check Valve is a spring-
loaded, plug-style check valve used to evacuate pipelines of
product or Cleaning-in-Place (CIP) media or to air-agitate
product in pipelines, tanks and other vessels. It also can air dry
the pipelines, which aids in the formation of a protective oxide
film thereby promoting corrosion resistance throughout the
pipeline system. The valve can help thoroughly mix and blend
the product in tanks and other vessels through air agitation,
improving product uniformity and product quality.

Application
The 62-174/326 Air Blow Check Valve is designed to evacuate
lines of product or CIP media, or for air agitation of product in
tanks and other vessels across the dairy, food, beverage, home-
personal care and chemical industries.

Alfa Laval 45BYMP
Control/Check Valve

Introduction
The Alfa Laval 45BYMP Check Valve is a Y-body ball check
valve designed to enable the product to pass through the valve
with no restrictions with a minimal pressure drop while
preventing reverse product flow in hygienic stainless steel pipe
installations. Capable of being installed in either a vertical or
horizontal position, the valve features a seat and stem angled at
approximately 45° to the pipe axis.

Durable and long-lasting, the valve operates at a wide range of

pressures and flow rates. Because the sealing check ball moves
completely out of the process flow when open, the valve offers
low pressure drop and easily handles viscous products or liquids
containing solid particles.

Application
The 45BYMP Check Valve controls flow, pressure control in gas
distribution systems and pressure reduction while preventing
reverse flow in connection with gas storage. It is widely used
across the dairy, food, beverage, home-personal care and
chemical industries.

Benefits
• Straightforward, robust, hygienic and reliable design and rests itself against the smaller diameter of the valve near its
• Fast-acting inlet. Should a reverse-flow situation occur, the opposing
• Minimal pressure drop pressure of the fluid will seat the ball firmly against the inlet of
• Leakproof the valve, preventing reverse flow.
• Authorized to carry the 3-A symbol
Certificate
Standard Design
The valve consists of a single-piece, stainless steel body with an
elastomeric ball (see Options for materials available). The "Y"
branch of the valve maintains a Tri-Clamp® connection along
with an associated Tri-Clamp, end cap, and NBR seal. The valve
is polished internally and externally and is authorized to carry the
3-A symbol.

Working principle
When liquid under normal pressure enters the inlet of the Alfa
Laval 45BYMP Check Valve, an elastomeric ball is pushed
upward into the "Y" branch (lower pressure area) of the valve.
When the liquid flow stops, the pressure within the valve
equalizes. The ball then returns from the "Y" branch of the valve

Alfa Laval SB Self-cleaning CO2-valve
Control/Check valves

Introduction
The Alfa Laval SB Self-cleaning CO2 Valve is a combination gas
supply-gas vent valve to control the flow of carbon dioxide in
tank top systems and other applications in order to vent and/or
pressurize a vessel. Fully cleanable and self-draining, this
hygienic valve provides safe, reliable and cost-effective gas
management.

Application
This gas management valve is designed to vent and/or
pressurize vessels used in hygienic applications, mainly used in
brewery industries.

Benefits
• Cost-effective, hygienic design
• Safe, reliable operation
• Minimized risk of overpressure and underpressure
• Self-cleaning and self-draining
• Straightforward installation

Working principle
The Alfa Laval SB Self-cleaning CO2 Valve uses a stainless steel
spring to force open the internal polypropylene valve body,
enabling the full flow of gas to pass through the valve in both
directions. The introduction of CIP fluid through a special drilled
opening in the valve body in a direction counter-current to the
spring force pushes the internal valve body into closed position
and ensures cleaning of all valve parts. The CIP flow is
approximately 3.5-4.GPM, depending on the valve size.

Standard design
The SB Self-cleaning CO2 Valve consists of a valve housing
comprised of two parts held together by a threaded connection.
Inside there is a valve body and a spring to keep the body in
open position. A special drilled opening in the valve body
ensures internal cleaning of the valve during Cleaning-in-Place
(CIP).

Typically positioned as an integrated part of the gas/CIP pipe at

the top plate, the valve can be mounted at an angle of 45°
(maximum) to the ideal vertical position.

Diaphragms

The diaphragms are available as soft elastomer (EPDM) as well as hard elastomers (PTFE/EPDM and TFM/EPDM).

103
The hard elastomers are supported by a soft elastomer (EPDM). The 2-piece design allows the two elastomers to work
independently of each other, thereby reducing tension caused by different thermal properties.

Diaphragms are available with 3 different types of connections: thread, bayonet and button connection.

• Threaded connections are used on soft elastomers ≥ 1"

• Bayonet connections are used on all hard elastomer ≥ 1/2"
• Button connections are used on all small sizes.

Material selection:
Each application has different working conditions and therefore different demands on the diaphragm. In order to select the most
suitable diaphragm for your application, the following factors should be considered:

• Working pressure
• Application temperatures
• Process fluids (product, cleaning liquid, sterilisation, passivation, etc.)

Soft elastomer (EPDM) is suitable for most applications and for high working temperatures. Including continuous steam application.

Hard elastomers offer the highest possible degree of chemical resistance. Our TFM (PFTE grade) elastomer is a more flexible material
and has some of the features of soft elastomer including for example low creep.

For further information, please see below or contact Alfa Laval for further guidance.

Alfa Laval Cast valve bodies with Optimized Flow utilize smaller diaphragm and topwork vs. Valve pipe dimension. Topwork being
either pneumatic or manual. This giving the benefit of having a slim and light weight valve.

Correct spare parts are easy to identify via the diaphragm tab, stating the giving size of diaphragm and topwork to be used on the
valve. See image below

Alfa Laval SMP-BC
Double seal valves

Introduction
The Alfa Laval SMP-BC Mixproof Valve is a hygienic pneumatic
double-seal valve that safely handles the simultaneous flow of
two different products through the same valve without any risk
of cross-contamination. Standardized and cost-effective, the
top-loaded valve is designed for quick leakage detection to
maximize product safety and low maintenance due to few
moving parts. It is often used in Cleaning-in-Place (CIP) lines
and can also be used in other systems handling products.

Application
The Alfa Laval SMP-BC Mixproof Valve is designed for hygienic
applications that require additional safety, leakage detection and
CIP in the dairy, food and beverage, personal care and many
other industries.

Benefits
• Hygienic double-seal mixproof valve
• Versatile, modular design meets most hygienic application
requirements
• Cost effective

Working principle
The Alfa Laval SMP-BC Mixproof Valve is controlled by means of
compressed air from a remote location. The valve is fitted with
two small pneumatic normally open (NO) valves, a detecting
valve and a CIP valve. The valve plug has two seals, which form
an atmospheric leakage chamber. Any product leakage is
discharged through the detecting valve. The leakage chamber
may be cleaned by supplying a CIP system into the detecting
valve. The SMP-BC is insensitive to water hammer in the
product line above the plug.

Standard design
The Alfa Laval SMP-BC Mixproof Valve consists of valve bodies,
bonnet, plug and an actuator. Two versions are available: a shut-
off valve with one valve body and a shut-off valve with two valve
bodies. A plug clip system and clamp rings secure the valve
bodies to the actuator. The valve can also be fitted with the Alfa
Laval ThinkTop V50 and V70 for sensing and control of the
valve.

Alfa Laval SMP-BCA
Double seal valves

Introduction
The Alfa Laval SMP-BCA Mixproof Valve with PTFE Diaphragm
is an aseptic double-seal valve designed for use under aseptic
conditions and sterilization involving high temperatures. Based
on the Alfa Laval SMP-BC, the SMP-BCA features a
straightforward design that keeps liquids separated using two
seals on the same plug with a leakage chamber in between.
With its PTFE face and reinforced EPDM rubber backing, the
diaphragm follows the plug movement of the upper valve body
and ensures no increase in the concentration of microorganisms
in the product during processing.

Application
This aseptic double-seal mixproof valve is designed for
extended shelf-life and aseptic applications in the dairy, food,
beverage, biotech, pharmaceutical and many other industries.

Benefits
• Aseptic double-seal mixproof valve
• Versatile, modular design meets most aseptic application
requirements
• Cost effective
• Easy to maintain
Standard design
Working principle The Alfa Laval SMP-BCA Mixproof Valve consists of valve
The Alfa Laval SMP-BCA Mixproof Valve is operated by means bodies, bonnet, stem with diaphragm unit, PTFE EPDM or FPM
of compressed air from a remote location. This aseptic valve is a plug seals and an actuator. The valve is assembled by means of
normally closed (NC) valve. A specially designed diaphragm unit clamp rings and a stem clip system for easy maintenance. It is
with a PTFE face and reinforced EPDM rubber backing ensures also available as a shut-off valve. The valve can also be fitted
sterile steam sealing prevents intrusion from the atmosphere with the Alfa Laval ThinkTop V50 and V70 for sensing and
and does not allow product residues to build up on the product control of the valve.
contact surface. The product lines are separated by two seals
and a sterile barrier chamber to prevent mixing the products and
to ensure immediate indication in the event of leakage from one
of the seals. Two small pneumatic normally open (NO) valves
control flow to and from the sterile barrier chamber. The barrier
chamber must be clean and sterile when the main valve is
closed.

Possible configurations
The Alfa Laval Unique Mixproof CP-3 offers a wide range of options, including:

Lower flush
The Alfa Laval lower flush option ensures CIP of the lower sealing element and the OD of the lower plug during seat push. This
option efficiently cleans the lower seal in the housing without the need for external CIP connections, supporting continuous
processing.

Balancing flexibility
The Unique Mixproof CP-3 valve has a lower balanced plug to avoid product mix, even in the event of pressure spikes in the system.
The upper plug can be configured with or without a balancer depending on the required performance.

144
SpiralClean
The Alfa Laval SpiralClean system makes it possible to clean the upper and lower plugs and leakage chamber by external CIP
connections. The system cleans more efficiently, uses less cleaning fluid by ensuring that a directional flow of CIP fluid reaches all the
surfaces in much less time than with conventional systems.

Spiral Clean of the leakage chamber is not depending on a special type of plug configuration, but can be added to any of the
available plug configurations. Here shown in combination with plug configuration #11

Pressure drop/capacity diagrams

Example to determine pressure drop:
Upper body size: 2". Balanced upper plug. Capacity = 80 gpm
Lower body size: 3". Balanced lower plug. Capacity = 80 gpm
Between bodies: Capacity = 60 gpm

Result:
From fig. 1, Δp = 0.9 psi through upper body.
From fig. 2, Δp = 0.25 psi through lower body.
From fig. 3, Δp = 1.7 psi seeing that:
1. The smallest body determines the curve for Δp between bodies.
2. Always choose the curve for balanced plugs if upper plug is balanced. If only lower plug is balanced, always choose the curve for
unbalanced.

Double seat valves

Introduction
The Alfa Laval Unique Mixproof Tank Outlet (TO) Valve is a
versatile, highly flexible double block-and-bleed valve for the
safe and efficient management of fluids at intersection points in
matrix piped systems. Specially designed for mounting directly
on the tank bottom or wall at the inlets and outlets, the valve
enables the safe handling of two different products or fluids
through the same valve. It provides full drainability and
cleanability all the way up to the tank--without any risk of cross-
contamination. Modular design and a wide variety of options
enable the valve to be customized to meet any process
requirement for all mixproof tank outlet operations allowing two
different products in pipeline and tank.

Alfa Laval Unique Mixproof PMO Curd CP
Double seat valves

Introduction
The Alfa Laval Unique Mixproof PMO Curd CP Valve is a highly
flexible, easy-to-service double block-and-bleed valve that is
specially designed for use in dairy applications with very large
particles or highly viscous fluids that require large openings up
to 1¾” (45 mm) in diameter.

Based on the well proven and exceptionally versatile principle of

the Unique Mixproof valves from Alfa Laval, it enables the
simultaneous flow of two different products or fluids through the
same valve, or the safe handling of one product while seat-lift
cleaning operations are being conducted in the other portion of
the valve – without the risk of cross-contamination.

The valve provides exceptional spillage-free operation and is

compliant with most hygienic standards, including the 3-A
Sanitary Standards, the Pasteurized Milk Ordinance and the
seat lift requirements of the US Food and Drug Administration.
With its modular design and a wide variety of options, the valve
can be customized to meet any process requirement and
provides low total cost of ownership. The valve plugs are balanced and not sensitive to pressure

simultaneous flow of two different products or fluids through the
same valve, or the safe handling of one product while seat-lift
cleaning operations are being conducted in the other portion of
the valve – without the risk of cross-contamination.

The valve provides exceptional spillage-free operation and

meets international standards for hygienic dairy processing. It
complies with the seat lift requirements of the 3-A Sanitary
Standards, the Pasteurized Milk Ordinance and the US Food
and Drug Administration, which enable seat lift cleaning in one
chamber while product flows through the other, thereby
eliminating downtime. All valve movements are detectable, and
the area of the vent tube is equal to or greater than the
connection pipe.

With its modular design, the valve can be customized to meet

any process requirement regardless of dairy size or capacity. It Standard design
maximizes uptime and provides low total cost of ownership.

Alfa Laval Unique Mixproof PMO® VTV
Double seat valves

Introduction
The Alfa Laval Unique Mixproof PMO® VTV is a flexible, easy-to-
service double block-and-bleed valve that is specially designed
for vertical mounting under a tank.

The valve is based on the well proven and exceptionally versatile

principle of the Unique Mixproof valves from Alfa Laval. It
enables one product in the tank on one side of the two valve
plugs while allowing cleaning media to flow through the valve
body for effective Cleaning-in-Place operations – without the risk
of cross-contamination.

The valve provides exceptional spillage-free operation and is

compliant with most hygienic standards, including the 3-A
Sanitary Standards, the Pasteurized Milk Ordinance and the
seat lift requirements of the US Food and Drug Administration.
With its modular design and a wide variety of options, the valve
can be customized to meet any process requirement and
provides low total cost of ownership.

Application
The Unique Mixproof PMO VTV is designed for continuous flow
management and process safety in hygienic processes where
product safety is at the top of the agenda across the dairy, food, Certificates
beverage and many other industries.

Benefits
• Complies with the Pasteurized Milk Ordinance (PMO)
• Enhanced product safety
• Cost-effective, spillage-free operation
• Optimized plant efficiency and enhanced cleanability
• Leakage detection and leakage chamber cleaning

Standard design
The Alfa Laval Unique Mixproof PMO VTV is comprised of a
series of base components, including valve body, valve plug,
actuator, and cleaning options and accessories that support a
wide range of applications. Leakage detection holes enable
visual inspection without requiring valve disassembly and
provide advance notification of parts wear. Few straightforward
moveable parts contribute to reliable operation and reduced
maintenance costs. The valve can also be fitted with the Alfa
Laval ThinkTop V70 for sensing and control of the valve.

State of the art

The Unique Mixproof PMO® VTV also provides a state of the art solution when there is no CIP pressure or flow from the tank side to
clean the seat and plug. The valve is self-cleaning, thanks to two Clean-in-Place (CIP) nozzles. The first nozzle is designed
specifically for plug cleaning. This double-acting nozzle projects cleaning solution through the tank connection, ensuring complete
cleaning of the seat contact surfaces as well as the shadow area of the tank port. The second is a rotating CIP nozzle incorporated
into the unit for optimum cleaning of the full-bore leakage chamber.

The valve can be connected with the tank via a weld in tank flange or a pipe end flange.

The 4″ model feature a 1.77 inches opening, which enables the passage of very large particles or efficient handling of high viscosity
fluids.

SpiralClean
The Alfa Laval SpiralClean system to clean the upper and lower balanced plugs and leakage chamber. The system cleans more
efficiently, uses less cleaning fluid by ensuring that a directional flow of CIP fluid reaches all the surfaces in much less time than with
conventional systems.

Pressure drop/capacity diagrams

Example to determine pressure drop:
Upper body size: 2". Balanced upper plug. Capacity = 80 gpm
Lower body size: 3". Balanced lower plug. Capacity = 80 gpm
Between bodies: Capacity = 60 gpm

Result:
From fig. 1, Δp = 0.9 psi through upper body.
From fig. 2, Δp = 0.25 psi through lower body.
From fig. 3, Δp = 1.7 psi seeing that:
1. The smallest body determines the curve for Δp between bodies.
2. Always choose the curve for balanced plugs if upper plug is balanced. If only lower plug is balanced, always choose the curve for
unbalanced.

Formula to estimate CIP flow during seat lift:

(for liquids with comparable viscosity and density to water):
Q = Kv ·√Δ p
Q = CIP - flow (m3/h).
Kv = Kv value from the above table.
Δ p = CIP pressure (bar).

Valve Sizing

Flow Coefficients (Kv)

The following formula and flow coefficient values enable you to select the correct regulating valve for your application.

Formula for water and other products with a specific gravity equal to 1.0:

Cvq Q

Formula for products with a specific gravity other than to 1.0:

Cvq Q

Where:

Q =Product flow rate in m3 per hour

SG =Specific gravity of product

∆ P = Pressure drop across valve in psi

(inlet pressure minus outlet pressure)

Example of Cv Calculation:
Determine the proper size valve for 175 GPM of water.

Inlet pressure of 11 psi

Outlet pressure of 2 psi

Solution: Inlet pressure (A) minus outlet pressure (B):

∆ P = 11 psi - 2 psi = 9 psi

How to Use Data to Select Valve Size

After the Cv factor for a specific application has been calculated, locate the factor on the following diagrams. Choose the curve
closest to the 50% stroke.

Using the above example, refer to the chart on the following diagrams you will find that the Cv factor (58.3) is marked on the chart.
You will find that a 2" valve crosses 1 Cv curve, 2½" 1 curve, 3" 3 curves and 4" 3 curves. The correct valve size to use is 2"
because Cv 58.3 crosses the curve closest to the optimum operating point 50%. Alternatively the 4" valve is also close to the 50%.

Alfa Laval Unique RV-P
Regulating valves

Introduction
The Alfa Laval Unique RV-P Regulating Valve is an automatic
hygienic regulating valve with an electro-pneumatic actuator for
use in applications that require precision control of flow as well
as pressure, temperature, and tank fluid levels.

Application
The Unique RV-P Regulating Valve is designed for precise flow
control in the dairy, food, beverage, biotechnology,
pharmaceutical and many other industries.

Benefits
• Precision flow control
• Advanced hygienic valve design
• Dedicated protection
• Reliable operation
• Large operating range

Standard design
Built on the Alfa Laval Unique SSV platform, the Unique RV-P
Regulating Valve consists of valve body, valve plug, lip seal, and
an external normally open (NO) actuator with bonnet. The
actuator is fitted to the valve body by means of a clamp. The Kv
value is flexible as lower element can be exchanged. Manual Certificates
and aseptic versions are available. Upon request, the valve can
also be supplied with a normally closed (NC) actuator.

Working principle
The Alfa Laval Unique RV-P Regulating Valve is controlled from a
remote location by means of compressed air. An actuator with
an integrated IP converter IP converter transforms the electrical
signal to a pneumatic signal. This signal conversion is based on
a highly accurate and reliable contactless AMR sensor, making it
insensitive to vibrations and pressure shocks. The pneumatic
signal is transmitted to the integrated positioner which operates
by means of the force-balance principle, ensuring that the
position of the actuator piston is directly proportional to the input
signal. Signal range and zero point can be adjusted individually.
The actuator can be used for split-range operation by using a
different measuring spring.

Alfa Laval SB Tank Pressure Regulator
Regulating valves

Introduction
The Alfa Laval SB Tank Pressure Regulator maintains the
working pressure in the vapour space, or at the top, of a
process tank during filling, processing and emptying. It generally
connects directly to the gas pipe or Cleaning-in-Place (CIP) pipe
that leads in to the tank top, or is incorporated into a flow panel.
This ensures process safety and effectiveness as well as
safeguards product integrity.

Application
This control valve typically regulates the pressure in tanks used
in the dairy, food, beverage, brewery and many other industries.
The valve easily integrates with an Alfa Laval SCANDI BREW®
tank top system.

Benefits
• Reliable, constant tank pressure control
• Variable pressure setting
• Optimized cleaning
• Built-in pressure gauge
• Fully cleanable with Cleaning-in-Place system

Standard design
The pressure regulator comprises a single valve unit including
pressure exhaust valve, pressure supply valve and connection
for pressure gauge. On top is a vent port with outlet connection.
A tank connection at the side branch is normally connected to
the pipe leading to the tank top. It is also possible to incorporate
the pressure regulator in a flow panel.

Working principle
The valve unit has a variable setting, which enables adjustment
of the relieving pressure to match the required working pressure
in the tank. When tank top pressure exceeds the preset
pressure, the regulator releases gas through the vent port—
either for atmospheric discharge or for collection. If the tank top
pressure decreases, a gas supply connection at the bottom of
the valve allows gas to flow into the tank.

Introduction
The Alfa Laval SB Pressure Exhaust Valve is a pneumatic
regulating valve that automatically releases pressure in a
hygienic process tank when it exceeds the set pressure. To
ensure safe pressure regulations at all times, the set pressure
can easily be adjusted manually or from a remote location that is
connected to the central control system.

Application
This pneumatic regulating valve is designed for use in process
tanks or vessels for hygienic applications in the brewery, food,
dairy, beverage and many other industries.

Alfa Laval CPM-I-D60
Regulating valves

Introduction
The Alfa Laval CPM-I-D60 Constant Pressure Modulating Valve
is a pneumatic regulating valve that maintains constant pressure
in hygienic process lines and stainless steel pipe systems at the
inlet side of the valve. Safe, reliable and easy to clean, this
regulating valve provides accurate pressure control, quickly
adjusting position to maintain the pressure at pre-set values
without any need for electronic control.

Application
This pneumatic regulating valve maintains uniform inlet pressure
in hygienic process lines across the dairy, food, beverage,
personal care and many other industries. The valve is often
installed downstream of separators and heat exchangers and
may also be used as an overflow valve.

Benefits
• Safe, accurate pressure control
• Self-draining design
• Excellent valve cleanability
• Easy to install and operate High hygienic level

Standard design
The valve consists of upper and lower valve bodies, an inlet
tube, a cover, a valve plug with diaphragm unit and clamps. The
diaphragm unit consists of a stainless steel disc, which is
divided into sectors, and flexible diaphragms, which are placed
on each side of the sectors. The cover and the valve bodies are
clamped together.

Working principle
The Alfa Laval CPM-I-D60 is controlled remotely by means of
compressed air. The valve operates without a transmitter in the

Alfa Laval Thermostatically Controlled Valve
Regulating valves

Introduction
The Alfa Laval Thermostatically Controlled Valve is a hygienic
regulating valve to control the temperature in cross-flow
membrane filtration plants. The thermostat is preset to control
either cooling or heating. When cooling, cooling medium is
either water or other coolants. When heating, the heating
medium is either hot water or steam. Quick signal conversion
makes it easy to adjust the temperature instantly.

Application
This temperature control valve is ideal for automatic regulation
temperature of the retentate in cross-flow membrane filtration
plants used in hygienic applications such as the dairy, food,
beverage, brewery, personal care and many other industries.

Benefits
• Hygienic regulating valve
• Straightforward, easy-to-use design
• Reliable and safe operation

Standard design
The Alfa Laval Thermostatically Controlled Valve is a normally
closed diaphragm valve that consists of a valve body, a valve
guide, a valve stem and an actuator. The thermostat includes an
AISI 316L stainless steel sensor, which is available with a 3", 2"
or 1" ISO 2852 clamp.

Working principle
The Alfa Laval Thermostatically Controlled Valve is operated by
means of an output air signal that controls the valve actuator. If
the set temperature differs from the actual operating
temperature (measured at the sensor), the screw in the dial
button should be loosened, the button set point at the
measured temperature, and then the screw should be tightened
again.

The working rate of the thermostat can be changed by

loosening the inlet throttle screw (max. 1/6 revolution). This will
result in faster activation of the membrane valve and reduce any
movement. The thermostat can be adjusted instantly, switching
from direct-acting mode to reverse-acting mode by exchanging
the spring and the adjustment screw on the rocker arm (see
drawing).

Interruption of operation
Impurities in the compressed air may cause choking of the filter and throttle. Normally, such impurities can be blown away by
opening the inlet throttle screw, which forces large amounts of air through the filter and throttle. The position of the throttle screw
should be noted so that it can be set to its original position after such a procedure.

Alfa Laval SB Anti Vacuum Valve
Safety valves

Introduction
The Alfa Laval SB Anti Vacuum Valve is a compact safety valve
that protects tanks from collapse or implosion due to internal
vacuum conditions. These conditions occur during emptying,
cool-rinsing after hot-cleaning, or caustic cleaning in a CO2
atmosphere. The compact, easy-to-clean safety valve fits onto
any closed process tank, optimizing the personnel safety,
reliability and performance of critical processes and maximizing
uptime.

Application
This safety valve is designed for use in hygienic processes in the
brewery, dairy, food, beverage and many other industries.

Benefits
• Greater process safety
• Low initial cost of investment
• Compact design
• Superior hygiene
• Easy installation

Standard design
The Alfa Laval SB Anti Vacuum Valve is a flange-mounted safety
valve. All product wetted steel parts are made of AISI 316L
stainless steel with a surface roughness of Ra< 32 μin; all other
steel parts are made of AISI 304L stainless steel. All product-
wetted seals are made of EPDM and all product-wetted
polymers are made of PEEK. The valve is PED 2014/68/EU-
compliant and available in two versions: either integrated in a
SCANDI BREW® tank top system or mounted on its own
counter flange.

Working principle
The Alfa Laval SB Anti Vacuum Valve is delivered with a
counterweight set and locked for an individual opening vacuum
to suit the tank or vessel design pressure. When a vacuum in
the tank or vessel is lower than the pre-set opening value, the
valve opens and lets in atmospheric air.

Cleaning In Place (CIP)

The Anti Vacuum Valve is cleaned, when closed, by the tank cleaning head, but this will not include the valve seating.

To include the valve seating in the cleaning cycle, there are two options:

CIP Kit 1 - Force opener; splash guard

The valve is force-opened during tank CIP. The cleaning of valve seat is dependent on cleaning jets from the tank cleaning head. Any
CIP liquid escaping the tank is contained by the splash guard and drains back in to the tank.

CIP Kit 2- Force opener; splash guard; CIP nozzle; CIP closing valve

The valve is force-opened during tank CIP. The cleaning of valve seat is performed by the CIP nozzle. All CIP liquid from the CIP
nozzle is contained by the splash guard and drains back in to the tank.

Note! Applying any of above CIP options provides that the tank is pressureless at the moment of force opening the
Anti Vacuum Valve

Alfa Laval SB Pressure Relief Valve
Safety valves

Introduction
The Alfa Laval SB Pressure Relief Valve is a hygienic safety valve
that removes excess liquid that creates overpressure in a
process tank or vessel due to overfilling. When pressure in the
tank exceeds a pre-set value, the pressure relief valve opens to
vent fluid in the event of liquid overfilling and closes when the
tank or vessel pressure has returned below the set point. This
prevents damage to the tank or vessel and help ensure safe
operations.

Application
This safety valve is designed to safeguard pressurized tanks and
vessels used in hygienic process lines in the brewery, dairy,
food, beverage and many other industries. The valve can be
integrated with a SCANDI BREW® tank top system.

Benefits
• Cost-effective, hygienic design
• Protection against tank overfilling and pressurization
• Superior hygiene
• Customized to meet process requirements
• Easy to clean

Standard design
The SB Pressure Relief Valve is a deadweight safety valve. It is
compliant with PED 2014/68/EU, EN 4126-1 and EN 764-7 and
available in two versions: integrated with a SCANDI BREW®
tank top system or mounted on its own counter flange.

Working principle
The Alfa Laval SB Pressure Relief Valve is delivered with
counterweight and is set and locked at the pre-set pressure,
specified by the customer as the opening pressure. When
pressure in the tank or vessel exceeds the pre-set opening
value, the valve relieves the excess pressure.

The opening pressure must be set at a value that is above the

tank working pressure: 1.45 PSI above for working pressures <
14.5 PSI, and 10% above for working pressures ≥ 14.5 PSI. The
valve should be seated horizontally. A maximum inclination of
10° is acceptable, but the lever arm must then point inward
toward the centre of the cylindroconical tank top.

Alfa Laval Unique Sampling Valve - Double Seat Valve
Sampling valves

Introduction
The Alfa Laval Unique Sampling Valve (Double Seat) is a double-
seat sampling valve that enables representative sampling in
hygienic processes under sterile conditions. It provides the high
accuracy, exceptional repeatability and excellent reliability
required for high-quality, cost-effective sampling. Either the
ergonomically designed handle or the actuator ensures
exceptional control during the sampling operation. It is possible
to sterilize the entire seat between sampling, thereby eliminating
the risk of cross-contamination.

Application
This double-seat sampling valve is specially designed for use in
hygienic applications across the dairy, food, beverage, brewery,
pharmaceutical, personal care and many other industries.

Benefits
• Safe, hygienic and contamination-free sampling
• Highly reliable operation
• Easy to operate and maintain
• Double seat with enhanced cleanability
• Modular design and easy to upgrade
• Sterilization possible

Standard design
The Alfa Laval Unique Sampling Valve (Double Seat) consists of
a valve body made of a single piece of stainless steel, either an
actuator for automatic operation or a handle for manual
operation, and a rubber membrane seal placed on the stem of
the actuator, which acts as a stretchable plug.

The valve is available in three sizes: Type 4, Type 10 and Type

25. A collared pipe, tank or Tri-Clamp connection is available.
The valve handles and actuators are interchangeable (see page
2).

Working principle
The Alfa Laval Unique Sampling Valve (Double Seat), with its patented technology, is designed for truly sterile sampling and ensures
higher cleanability and sterilization of the valve seat and pipe connections. The double-seat sampling valve has three positions: open,
shut and sterilization. It can be operated manually or automatically using a pneumatic actuator.

• Open position: To start the sampling process

2900-0076

Manual valve: rotate the handle in a counterclockwise direction to open the valve. Pneumatic valve: open the valve by activating the
actuator. This retracts the valve stem and membrane seal, which enables the product to flow freely through the open valve.

• Shut position: To stop the sampling process

2900-0077

Manual valve: rotate the handle in a clockwise direction to close the valve. Pneumatic valve: shut the air supply to stop the flow of
product from the valve. In closed position, the valve body is now ready for sterilization. If steam is used for Sterilization-in-Place, the
use of an optional pressure relief valve on the outlet is recommended to ensure proper steam temperature in the valve.

313
 • Sterilization position

2900-0079

Manual valve: rotate the handle clockwise to the steam position. Pneumatic valve: apply air to the steam connection. This extends
the inner spindle of the valve head into the inner seat and stops product flow in the valve port. At the same time, the outer spindle of
the valve retracts and lifts the membrane seal away from its normal seat. Now it is possible to access the hard-to-reach areas on the
seat surface, ensuring thorough sterilization and making the Unique Sampling Valve (Double Seat) a solid and reliable choice to
achieve 100% representative sampling.

If steam is used for Sterilization-in-Place, the use of an optional pressure relief valve on the outlet is recommended to ensure proper
steam temperature in the valve.

TECHNICAL DATA
Temperature
Temperature range: 33.8°F - 266°F
Max. sterilisation temperature, dry steam (29 PSI): 249.8°F

Steam must be dry, since condensate will damage the membrane seal. It is recommended that the membrane seal is changed every
500 samples/sterilisations or in accordance with working conditions or experience.

Pressure
Max. working pressure: 600 kPa (87 PSI)
Min. working pressure: 0 kPa (0 PSI)

Working principle
The Alfa Laval Unique Sampling Valve (Single Seat) is designed for standard hygienic sampling. The single-seat sampling valve has
two positions: open and shut.
• Open position: To start the sampling process

2900-0076

Manual valve: rotate the handle in a counterclockwise direction to open the valve. Pneumatic valve: open the valve by activating the
actuator. This retracts the valve stem and the membrane, which enables the product to flow freely through the open valve.

• Shut position: To stop the sampling process

2900-0077

Manual valve: rotate the handle in a clockwise direction to close the valve. Pneumatic valve: shut the air supply to stop the flow of
product from the valve. In closed position, the valve body is now ready for sterilization. If steam is used for Sterilization-in-Place, the
use of an optional pressure relief valve on the outlet is recommended to ensure proper steam temperature in the valve.

Upgrading to the Alfa Laval Unique Sampling Valve (Double Seat) is possible to realize higher cleanability and thorough sterilization of
the valve seat and pipe connections.

product transfer. A micro sample port enables aseptic
introduction of pure yeast culture by means of a syringe.
Compliant to PED 2014/68/EU.

Working principle
The SB Carlsberg Flask is filled to its net capacity with wort,
corresponding to approximately 80% of the total volume.
Sterilization takes place using an autoclave, a gas burner or an
electric hotplate. It is then placed in a refrigerator or a cold room
to cool the wort to the desired working temperature. The cold
wort is aerated through the membrane sample valve connected
to the aeration lance.

Yeast culture can be introduced aseptically through the

membrane fitting by means of a syringe. Alternatively, dry yeast
culture can be transferred to the flask through the empty filter
housing.

Alfa Laval Koltek Valves
Shutter valves

Introduction
The Alfa Laval Koltek Valve can be either manually or
pneumatically operated. The valve is suitable for use with
products that are highly viscous, contain large particles, or have
strict requirements to minimize pressure loss.

Application
The koltek valve is designed for use in the food, chemical,
pharmaceutical and many other industries.

Benefits
• Flexible in-line valve with three-port flow diversion
• Minimized pressure loss
• Hygienic design
• Capable of handling products highly viscous, contain large
particles, or have strict requirements to minimize pressure
loss

Standard design
The koltek valve consists of a rigid body with an internal
cylindrical bore, a PTFE shutter and three ports for pipe
connection. The two lids have guide rings or bearings for an
internal shaft, which supports and positions the shutter. The
a double-acting actuator. The single-acting actuator operates
stainless-steel handle for manual operation or the actuator for
with one main piston whereas the double-acting actuator
automatic operation is fitted to turn the shaft. The actuator
operates with two main pistons.
consists of a system of cylinders and one or two main pistons
interconnected with a toothed bar which interacts with a gear
wheel on the valve shaft. The system is insensitive to pressure
shocks in the valve.

Working principle
The Alfa Laval Koltek Valve is operated by means of a handle or
an actuator. A spring system presses the shutter against the
inside cylindrical surface of the valve body thus ensuring
complete tightness.

The air-actuated valve can be fitted with an Alfa Laval

ThinkTop® V50 or V70 control unit, or an indication unit installed
laterally for remote indication of the valve position.

The manually operated valve can be fitted with indication units

(used for Alfa Laval LKLA actuators) installed laterally. The valve
actuator is available in two versions: a single-acting actuator or

 Note!
For the diagrams the following applies:
Medium: Water (68° F/20° C)
Measurement: In accordance with VDI2173
Pressure drop can also be calculated in Anytime configurator

Pressure drop can also be calculated with the following formula:

Q = Cv x √Δp

Where

Q = Flow (gallon/minute).

Cv = gallon/minute at a pressure drop of 1 psi (see table above).

Δ p = Pressure drop in psi over the valve.

How to calculate the pressure drop for an ISO 2.5" shut-off valve if the flow is 160 gallon/minute.

2.5" shut-off valve, where Cv = 128 (See table above).

Q = Kv x √Δp

160 = 128 x √Δp

(This is approx. the same pressure drop by reading the y-axis above)

Kv = m3/h at a pressure drop of 1 bar.

For other pressure drops than 1 bar the flow can be calculated with the following formula:

Q = Kv x √Δp

Where

Q = Flow in m3/h.

Kv = See above.

Δ p = Pressure drop in bar over the valve.

Example:
428
Plug Kv 75

Q to be calculated at ∆p = 2 bar:

Q = 75 x √2 = 106 m3/h

or at 50% stroke:

Q = 0.5 x 75 x √2 = 53 m3/h

Pressure drop/capacity diagram:

The plugs have linear characteristics. This means that a certain amount of throttling, by reducing the stroke, results in a proportional
reduction of the flow if the pressure drop remains unchanged.
