PRODUCT OVERVIEW

THE SLIDING GATE SEAT: A BETTER DESIGN

SIMPLE CONCEPT, SUPERIOR PERFORMANCE

You will notice something different in a Jordan valve . . . the sliding gate seat.
A remarkably simple concept that offers superior performance and benefits
not found in traditional rising stem and rotary valves.

The sliding gate seat is made up of two primary parts: a movable disc and
stationary plate with multiple orifices. Together, this seat set achieves levels
of performance, reliability and accuracy that are hard to find in other valve
designs.

ADVANTAGES

Quiet Operation

Compared to conventional globe and cage designs, the sliding

gate seat generates between 5-10dB less noise. You won't
find a premium price adder for "low-noise trim!" The sliding
gate valve is inherently quieter than other types of valves
because:

•• The disc and plate remain in constant contact, eliminating

the chatter found in globe-style designs

• The straight-through flow passage minimizes turbulence

"Massive" globe or
cage style valve
found in globe and rotary designs, a prime cause of valve
noise

• The multiple orifices in the plate and disc divide the flow
into smaller flow streams resulting in less noise

Smaller, lighter
Size and Weight sliding gate
wafer-design
control valve
As the line size increases, so too does the size and weight of
the valve. Because of the short stroke length, a sliding gate
valve is typically smaller and lighter weight than a globe/cage
style valve.

For the Mark 75 Series control valve, the shipping size, weight,
packing waste and costs decrease dramatically due to the
wafer style design.

Reduced Turbulence

When throttling, the control member of a rotary control valve

will direct the flow to the sealing area of the seat, causing
premature seat leakage.

The tortuous flow path of a globe style design creates

greater turbulence, noise and wear - reducing seat life and
compromising control. In flashing or cavitating service,
damage to the valve body is common, mitigated only through
expensive material upgrades or elaborate trim configurations.

The multi-orifice straight through flow path of the sliding gate

reduces turbulence and leads to quieter operation, reduced

wear, longer seat life and better control.
The tortuous flow of a traditional globe style valve.
For example, when combined with the ultra-compact wafer
body design of the Mark 75 Series, erosion of the seats and
valve body is virtually eliminated. Dramatic cost savings can
be realized.

Straight-Through Flow

The seat set is perpendicular to the flow, unlike the

traditional globe style design. With straight through flow,
the turbulence is reduced and superior trim life is achieved.

The sliding gate design provides exceptional low flow control

since the flow works with the seat and not against it. In a
typical globe style design, the flow goes underneath the
plug, working against the plug. With the sliding gate, the flow
pushes the disc against the plate, helping to hold the desired
setpoint. This also enables the disc and plate to lap and clean
themselves as the valve modulates. The sliding gate design

Short Stroke, Fast Response

The total stroke length is just a fraction of the equivalent In control valves, the sliding gate allows the use of reduced
globe valve. In pressure regulators, the stroke length is air consumption and weight minimization. The short stroke
typically 1/3 that of a globe valve, reducing the amount of reduces packing wear and lengthens the diaphragm life.

yields and profits.

Easy to Maintain

The simple design of the sliding gate valve makes

maintenance easy to perform. Disassembly of the valve is very
simple, and since the seats are not pressed or screwed into
the valve body, they conveniently lift out. Should your flow
requirements change, interchangeable Kv's (Cv's) are
available in coefficients as low as 0,0007 (0.0008) and as
high as 519 (600) (depending on body size).

• Eliminates Damaging Chatter: The upstream pressure

holds the disc in constant contact with the plate. This
prevents the sudden, damaging (and noisy) contact which
occurs in some globe designs. The constant contact
between the disc and plate actually generate a self-lapping
effect which results in less friction and tighter shutoff than
when the valve leaves the factory.

JORLON DIAPHRAGM
The Jorlon diaphragm extends the life of your regulators and reduces the overall cost of ownership. This diaphragm was developed
as an alternative to the standard SST diaphragm.

Jorlon is a proprietary modified PTFE material that positively impacts regulator reliability, performance and service life. It is the
standard and preferred diaphragm in most regulator applications and provides many benefits.

• Chemical Compatibility: since Jorlon is PTFE based, it is • Long Life: Jorlon has been extensively tested for

MK608 Gas Pressure Regulator, Balanced Plug

The Mark 608 gas pressure regulator is used on large tank blanketing applications
or other low pressure gas regulation. In a tank blanketing application, the Mark 608
is used to control the flow of the blanketing gas into the tank to maintain the proper
