Application
This valve is used for preventing the back-going of medium in
pipelines and equipments and the pressure of medium will
bring the result of opening and closing automatically. When
the medium is back – going, valve disc will automatically close
to avoid accidents.

Features
• This valve is tightly sealed, without under the pressure
wafer test.
• Safe and reliable in operation, high resistance.

Fire Protection Pressure Relief Valve

Description
The Cla-Val Model 50B-4KG1 (Globe) / 2050B-4KG1
(Angle) Pressure Relief Valve is designed specifically to
automatically relieve excess pressure in fire protection
systems. This pilot controlled relief valve maintains
constant system pressure at the pump discharge within
very close limits as demands change.

Operation is completely automatic and pressure

settings may be easily changed. This valve can be
used for pressure relief, pressure sustaining, back
pressure, or unloading functions in a bypass system.
This fast opening, slow closing relief valve provides
system protection against high pressure surges on
pump startup and pump shut down by dissipating the
excess pressure to a safe location.

INLET OUTLET

The Cla-Val Model 50B-4KG1/2050B-4KG1 Pressure Relief Valve pilot control system is a normally closed pilot operated valve that will open to relieve
excess pressure with accurate precision. The CRL (Item 2) pilot can be easily adjusted to a wide range of pressure settings. While monitoring the
pressure gauge (Item 5), the CRL adjustment screw can be turned clockwise to INCREASE pressure or counterclockwise to DECREASE pressure. The
CRL adjustment screw is protected by a screw-on cover, which can be sealed to discourage tampering.

2. Open by-pass valve and “B” butterfly throttle valve 5. Refer to pump GPM requirement and
3. Purge meter, located on venturi, as follows: adjust throttle valve to meet the requirement.
a) Open station shut-off valves on venturi & vent valves 6. After the test, open valve “A” and
attached to meter. When a steady stream of water close the by-pass and “B” valves.
passes through hose, meter is purged of air.
b) Close the vent valves after purging.

Control pressure switch series FF 4

0.11 up to 250 bar, ample wiring room, easy to adjust
high repeatability of set switchpoints, easily read scale �����

Applications
Air compressors, water pumps, booster pumps, firefighting equipment,
oil supply equipment .

Description
TIVAL pressure switches of the FF 4 series are suitable for a wide range
of applications. They can be utilized for:
 Monitoring and controlling the pressure of liquid or gaseous media in
pipelines, tanks, vats, pressure vessels and apparatus.
 Applications in process control, cooling, pneumatics and hydraulics.
 Pressure monitoring of cooling circuits and lubrication systems on
various types of machinery.
 Automatic switching of pump and compressor motors for supplying water
to dwellings, booster pumps, firefighting equipment and on compressed
air systems.
103 mm
Mode of operation
151 mm
The pressure of the monitored medium operates against a flat diaphragm,
75,5 mm bellows or plunger (depending on pressure range). A system of levers and
springs work on a snapaction cascade switch of high vibration resistance,
a
14 mm ensuring flutterfree switching. With no pressure on the diaphragm contact 1-2
is closed. This can be used as an „ON“ signal for a pump or compressor motor.
40,5 mm
If pressure exceeds the upper switchingpoint, contact 1-2 opens and contact
5,5 mm 1-4 closes. The connected motor will be switched off. Contact 1-4 is often
40 mm used to indicate the „off“ condition.
50 mm
84,5 mm 77,5 mm
Contact 1-2 will close again, when the pressure on the diaphragm has
dropped below the set lower switchpoint. Upper and lower switch points can
FF 4-2, FF 4-4, FF 4-8, be adjusted independently of each other using a screwdriver. The two switch
FF 4-16, FF 4-32 points are indicated on the scale inside the unit.

Change-over contact with manual reset min.:

If the pressure drops below the set value, contact 1-4 opens and contact
1-2 closes and locks. When the pressure has risen above the set value, the
contact can be unlocked with the manual reset button.
103 mm
Change-over contact with manual reset max.:
151 mm
If the pressure rises above the set value, contact 1-2 opens and contact 1-4
75,5 mm closes and locks. When the pressure has dropped below the set value, the
contact can be unlocked with the manual reset button.
14 mm
57 mm
Pressure connection, pressure sensing element, switch mechanism and
electrical terminals are fitted on a die-cast aluminum-alloy base. The scale
and switch are protected against environmental effects by an impact-resistant,
40,5 mm
5,5 mm transparent polycarbonate cover, (CTI 200-225) and can be lead-sealed.

Note: 1. The BS-1 and BS-1T are pressure-proof models. The rest of models are not pressure-proof.
2. The BS-1 that uses SUS304 for clamping sections and screws of PT1/2 specifications is called BS-1S1.
3. The BS-1 that uses SUS304 for clamping sections is called BS-1S and one that uses SUS316 is called BS-1S2.
4. When using the BS-1T in liquids with low specific resistance, provide a large clearance between Electrodes. This clearance must be var-
ied depending on the specific resistance, for example, approximately 1 m for acid or alkali liquids.
