The Type 92W pressure-reducing regulator for liquid
service includes either a Type 6492H or a Type 6492L
pilot (Figure 1). This reliable, dependable regulator
uses time-proven design concepts.
•
Type 92W main valve and Types 6492H and 6492L
pilots use machine-lapped seating surfaces, a time-
proven design which minimizes seat leakage when
the downstream demand is zero and the regulator
is shutoff.
• Steel constructions
are available to help resist piping stresses.
• Compact construction
reduces installation space requirements. Supply
pressure to the pilot is supplied from the inlet side
of the main valve through factory-piped tubing; with
a standard pilot, this means no separate pilot
supply pressure is required.
•
Friction-reducing bellows seal on
the pilot stem and large pilot diaphragm areas
yield good sensitivity.
• Pilot valve plug and
seat can be removed for inspection or maintenance
without disassembling piping connections and
without removing the diaphragm. Pilot inlet screen
is easily removed with the seating parts for
inspection and cleaning. Diaphragm can be
removed without disturbing the seating parts.
• Pilot with optional tapped
spring case is available for use either with an air
loading regulator for remote adjustment of outlet
pressure setting or, when all compression is
removed from the pilot control spring, with a
solenoid or switching valve for on-off service.

Figure 3. Typical Pressure-Loaded Pilot Installation
Pilot supply pressure is piped from the main
valve inlet (Figure 2) to the pilot inlet connection.
Downstream pressure registers on the main valve
pistons through the downstream control line and then
on the pilot diaphragm.
When increased downstream demand lowers the
downstream pressure to a value below the setting of
the pilot control spring, this spring forces the pilot valve
plug open to increase the loading pressure on the
main valve pistons. At the same time, the increased
demand lowers the downstream pressure on the
main valve piston(s). This opens the main valve plug,
increasing ow to the downstream system to satisfy
the increased demand and to restore downstream
pressure to the setting of the pilot control spring.
Decreased downstream demand increases the
downstream pressure registered on the pilot
diaphragm. The increased pressure overcomes the
force of the pilot control spring and allows the pilot
valve plug spring to close the pilot valve plug. As the
pilot valve plug closes, excess loading pressure bleeds
to the downstream system through the pilot bleed
restriction. At the same time, decreased downstream
demand increases the downstream pressure
registered on the main valve piston(s). This allows
the main valve spring to close the main valve plug,
reducing ow to the downstream system in response
to the decreased demand.
With a pilot for pressure-loaded service (Figure 3), the
operation is the same as for a standard pilot except
that the pilot control spring force on the pilot valve
plug is aided by pneumatic pressure from the loading
device. With a pilot for on-off service, the only force
acting on top of the pilot diaphragm is pneumatic
pressure provided by the solenoid or switching valve.

Table 3. Flow Capacities in U.S. Gallons per Minute (l/min)(1) of Water (continued)
The Type 92W regulator should be installed and
used in accordance with governmental codes and
regulations. Although this regulator minimizes
leakage under shutoff conditions, downstream
overpressure protection must be provided by the
user. The pressure and temperature limitations in
the specications table must be observed and the
downstream equipment protected.
A Type 92W regulator may be installed in any
orientation, but to obtain maximum ow capacities in
some instances, outlet piping will have to be swaged
up above the given body size. Liquid pressure control
systems should be designed using good engineering
practices to eliminate quick starting or stopping of the
ow stream, which can produce water hammer.
A downstream control line is required but is not
furnished with the Type 92W regulator. Additionally,
an adjustable loading pressure regulator and loading
pressure piping are required for pressure-loading pilot
regulators, while an on-off or solenoid valve is required
for on-off pilot regulators.
Table 3 gives maximum and minimum regulating
capacities in U.S. gallons per minute of water (multiply
by 0.2271 to convert to cubic meters per hour of
water).To determine regulating capacities at pressure
settings not given in Table 3 or to determine wide-open
capacities for relief sizing at any inlet pressure, use the
Catalog 10 liquid sizing procedures in conjunction with
the appropriate liquid sizing coefcients (Cv and Km).
Convert to cubic meters per hour according to the
preceding paragraph if necessary.
When ordering, specify:
• Temperature range
• Inlet pressure range (maximum, normal, minimum)
• Outlet pressure setting
• Flow rate range (maximum, normal, minimum)
• Body size
Refer to the Specications on page 2. Review the
descriptions to the right of each specication, and
specify the desired choice wherever there is a selection
to be made. If not otherwise specied, the pilot control
spring is factory-set at the approximate mid-range.
Be sure to specify the type of regulator desired
(standard pilot or pilot with optional tapped spring
case). Refer to separate bulletins for information on
loading regulators for use with pressure-loaded pilots.
