Type 92C Steam Regulator
!

WARNING

Fisher® regulators must be installed,
operated, and maintained in accordance
with federal, state, and local codes, rules
and regulations, and Emerson Process
Management Regulator Technologies,
Inc. instructions.

Introduction
Scope of the Manual
This instruction manual provides installation,
maintenance, and parts ordering information for the
Type 92C steam self-powered control valve and the
Type 6392 pilot. Both the pilot-operated and the
pressure-loaded constructions are covered. The
Type 92C is also available with a Type 6492HM or
6492HTM safety override pilot. The pressure-loading
device and accessories used with this valve are
covered in other manuals.

Figure 1. Type 92C Pilot-Operated Regulator

1301 Series regulator or 670 Series panel-mounted
regulator may be used as the loading regulator.
A Type 6492HM (or 6492HTM) safety override pilot is
also available for the Type 92C. The Type 6392 pilot is
used in a series installation with the Type 6492HM (or
6492HTM) safety override pilot installed on the upstream
valve. The Type 6492HM (or 6492HTM) safety override
pilot senses pressure downstream of the second valve,
and prevents pressure from rising above safe operating
pressure in the event the downstream valve fails. This
system is approved by ASME B31.1-1989, 122.14.2.A,
and can replace an ASME safety valve when vent
piping is not practical and upstream pressure does not
exceed 400 psig / 27.6 bar. Local codes and standards
may require approval by an appropriate authority prior
to installation.

Description
The Type 92C steam regulator is a gray cast iron,
steel, or stainless steel pressure-reducing regulator
for steam or hot air service. This regulator is available
with a Type 6392 pilot for use as a pilot-operated
regulator (Figure 1) or without a pilot for use as
a pressure-loaded regulator. The pilot-operated
version uses inlet pressure as the operating medium;
no separate air supply is required. The pressureloaded version is used where remote adjustment of
the regulator pressure setting is required; a 67 or

WARNING

The Type 92C safety override system
does not provide positive shutoff in
dead end service. It is intended for
large distribution systems where steam
leakage will condense before steam
pressure builds up. Downstream piping
and components must be rated for
maximum upstream steam pressure for
dead end service. Failure to do so could
cause personal injury or death.

Type 92C
Principle of Operation
Pilot-Operated Regulator
Refer to Figure 5. Pilot supply pressure is piped from
the inlet side of the main valve to the pilot inlet
connection. Downstream pressure registers under the
main valve diaphragm through the pitot tube and under
the pilot diaphragm through the downstream control line.
When downstream pressure decreases to a value
below the setting of the pilot regulator spring, the pilot
spring forces the pilot valve plug open, increasing
the loading pressure on the top of the main valve
diaphragm. The increased loading pressure on top of
the main valve diaphragm and decreased downstream
pressure under the main valve diaphragm force the
main valve diaphragm and stem downward. This
opens the main valve plug, and increases flow to
the downstream system, thus restoring downstream
pressure to the setting of the pilot regulator spring.
When downstream pressure increases it registers
under the pilot diaphragm and overcomes the force of
the pilot spring. This allows the pilot valve spring to
close the pilot valve plug and causes excess loading
pressure to bleed to the downstream system through
the pilot bleed hole. At the same time, increased
downstream pressure registers under the main valve
diaphragm. The decreased loading pressure on top of
the main valve diaphragm and increased downstream
pressure under the main valve diaphragm force
the main valve diaphragm upward. This allows the
main valve plug spring to close the main valve plug,
reducing flow to the downstream system.

Pressure-Loaded Regulator
Refer to Figure 7. With a pressure-loaded regulator, a
remote, adjustable loading regulator provides loading
pressure to the top of the main valve diaphragm.
Downstream pressure registers under the main valve
diaphragm through the pitot tube.
When downstream pressure decreases, it registers
under the diaphragm and allows the stem and plug
to move downward, thereby opening the valve to
increase downstream pressure.
When downstream pressure increases, it registers
under the diaphragm and forces the stem and plug
to move upward. The upward force of the spring
causes the valve to close, which decreases flow to

the downstream system thus decreasing downstream
pressure. In hot air service, supply air above the
diaphragm becomes compressed and is vented to the
atmosphere. If a steam supply is used, the steam is
vented downstream.

Safety Override Pilot Principle
of Operation
Refer to Figure 6. Once placed in operation, the
upstream Type 6392 pilot senses the intermediate
pressure between both valves, and the Type 6492HM
(or 6492HTM) pilot senses downstream pressure of
the second valve. As demand for flow increases,
intermediate pressure will fall causing the Type 6392
pilot to open. As the Type 6392 pilot valve opens,
loading pressure to the main valve increases, opening
the main valve.
The Type 6492HM (or 6492HTM) safety override
pilot remains open because its setpoint is above
the setpoint of the downstream valve. In the
unlikely event that the downstream valve fails open,
downstream pressure will rise above the downstream
valve’s setpoint. This pressure is sensed by the
Type 6492HM (or 6492HTM) safety override pilot. As
downstream pressure increases the safety override
pilot closes, reducing loading pressure to the main
valve, which positions the main valve to maintain
downstream pressure as specified per ASME Boiler
and Pressure Vessel Code, section VIII.
In the event that the upstream valve fails, the
downstream regulator will prevent downstream
pressure from rising above safe operating levels.
It is recommended to install some type of warning
system, such as a sentinel relief valve, to warn the
operator that a valve has failed in the system. This
will prevent prolonged operation with one valve, which
could cause valve trim wear and noise associated with
operation at high differential pressures.
When operating in most steam systems, valve
setpoints should be in strict accordance to
ASME Boiler and Pressure Vessel Code, section VIII.
The Type 6492HM (or 6492HTM) safety override
pilot should be set at 10 psig / 0.69 bar or 10% above
maximum downstream operating pressure of the
second valve, whichever pressure is greater. For
example, most HVAC systems operate at 15 psig /
1.0 bar, so the safety override pilot should be set no
higher than 25 psig / 1.7 bar.

WARNING

Personal injury, equipment damage,
or leakage due to escaping steam
or bursting of pressure-containing
parts may result if this regulator is
overpressured or is installed where
service conditions could exceed the
limits given in Specifications section on
page 2 and on the appropriate nameplate,
or where conditions exceed any ratings
of the downstream piping or piping
connections. To avoid such injury or
damage, provide pressure-relieving or
pressure-limiting devices to prevent
service conditions from exceeding
those limits. Type 92C regulators and
their installations should be checked
for compliance with all applicable codes
such as the ANSI B31.1-1977 Power
Piping standard and the ASME Boiler and
Pressure Vessel code.
Use a qualified personnel when installing, operating,
and maintaining a Type 92C regulator. Make sure
that there is no damage to or foreign material in the
regulator and that all tubing and piping are clean
and unobstructed. Install the regulator so that flow
direction matches the arrow marked on the regulator
body. Some typical Type 92C regulator installations
are shown in Figures 3 and 4.
The Type 92C regulator may be installed in any
orientation. However, the regulator should not be
6

installed in a tall vertical pipeline where condensate
could collect and create a pressure head affecting
regulator performance.
Apply steam-compatible pipe compound to the
external pipeline threads. Then, using acceptable
piping procedures, install the regulator into
the pipeline.
If continuous operation of the system is required
during inspection and maintenance, install a threevalve bypass around the regulator. If the flowing
medium contains solids, install a proper size strainer
upstream of the regulator.

Pilot-Operated Regulator
The Type 6392 pilot has three 1/4 NPT connections
located in the pilot body. For proper operation of
a pilot-operated regulator, the pilot supply and the
regulator loading connections should be installed
parallel to the flow direction arrow marked on the pilot
body as shown in Figure 10, and the downstream
control line should be installed in the pilot body
connection as shown in Figures 3 and 10. If a pilotoperated regulator is ordered, the pilot supply and
the regulator loading connections will be made at
the factory.
Note
Pilot is shown here above the main valve
body for illustration purposes only. See
Figures 1 and 10 for actual pilot position
and appearance of pilot-supply line and
loading-pressure tubing.

Note
Since a clogged vent may cause
improper regulator functioning, install
and maintain the Type 92C regulator so
that the Type 6392 pilot spring case vent
remains clear and unobstructed.
To install a pilot-operated regulator:
1. C
onnect a downstream control line of at least
1/4-inch / 6.4 mm diameter pipe bushed down
to the 1/4 NPT control line connection in the
pilot body.
2. F

the pipeline control line connection in a section of
straight pipe at least 10 pipe diameters away from
the regulator or swage.

device. In all cases, check the pressure setting to
make sure it is correct for the application.

Startup
The maximum inlet pressure for a specific construction
is stamped on the main valve nameplate. Use
pressure gauges to monitor upstream and downstream
pressures during startup.
To put the regulator into operation:
1. Open the control line shutoff valve.
2. For a pilot-operated regulator, open the
downstream block valve.
For a pressure-loaded regulator, open the shutoff
valve in the pressure-loading piping or tubing.

3. D
o not locate the pipeline control line connection
in an elbow, swage, or other area where
turbulence or abnormal velocities may occur.

3. Slowly open the upstream block valve.

4. If the pilot is mounted with the control line in a
position other than horizontal, make sure the
control line is sloped away from the pilot so that
condensate can drain into the pipeline.

5. T
o adjust the downstream pressure, follow the
appropriate procedure:

4. If a bypass line is used, slowly close the bypass
line block valve.

a. F
or a pilot-operated regulator, loosen the
jam nut (key 15, Figure 9). Turn the adjusting
screw (key 16, Figure 9) into the spring case
to increase the downstream pressure. Turn
the adjusting screw out of the spring case to
decrease the downstream pressure. When the
required downstream pressure is maintained
for several minutes, tighten the jam nut to lock
the adjusting screw in position.

b. F
or a pressure-loaded regulator, refer
to the Instruction Manual of the pressureloading device for downstream pressure
adjustment procedures.

5. Install a shutoff valve (not a needle valve) in
the control line to completely isolate the pilot
during maintenance.
6. Install a pressure gauge in the control line or near
the regulator to aid in setting the outlet pressure.
Each pilot-operated regulator is factory-set
for the pressure setting specified on the order. If
no setting is specified, the unit is factory-set at
30 psig / 2.1 bar. In all cases, check the spring
setting to make sure it is correct for the application.

Pressure-Loaded Regulators
To install a pressure-loaded regulator:
1. Install a shutoff valve in the pressure-loading
piping or tubing.
2. C
onnect the piping or tubing to the 1/4 NPT
connection in the diaphragm flange (key 2, Figure 8).
If the loading regulator used with the pressureloaded regulator does not provide internal relief, an
atmospheric bleed (e.g., no. 60 drill size) is required
if the loading supply is air, or a downstream bleed
line is required if the loading supply is steam. This
installation is shown in Figure 4.
The pressure setting of a pressure-loaded regulator
is adjusted and determined by the pressure-loading

Safety Override Pilot Startup
and Adjustment
1. Loosen adjusting screws of the Type 6492HM (or
6492HTM) safety override pilot and Type 6392
intermediate pilot on the upstream valve until there
is no spring load. The screws should turn freely
by hand.
2. Loosen the adjusting screw of the Type 6392
pilot on the downstream valve until there is no
spring load.
3. T
ighten the Type 6492HM (or 6492HTM) safety
override pilot of the upstream valve all the way in
to its highest spring setting.
