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.
The Type 92C steam regulator is a 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 pressure-
loaded version is used where remote adjustment of the
regulator pressure setting is required; a 67 or 1301 Series
regulator or 670 Series panel-mounted regulator may be
used as the loading regulator.
Figure 1. Type 92C Pilot-Operated 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.

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 ow 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 ow to the downstream system.
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 ow 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.
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 ow 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 specied 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).
Type 92C

Use a qualied 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 ow
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
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 three-valve
bypass around the regulator. If the owing medium
contains solids, install a proper size strainer upstream
of the 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 ow 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 pilot-operated
regulator is ordered, the pilot supply and the regulator
loading connections will be made at the factory.

To install a pilot-operated regulator:
1. Connect 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. For both body-sized and swaged pipelines, locate
the pipeline control line connection in a section of
straight pipe at least 10 pipe diameters away from
the regulator or swage.
3. Do not locate the pipeline control line connection
in an elbow, swage, or other area where
turbulence or abnormal velocities may occur.
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. 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 specied on the order. If
no setting is specied, 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.
To install a pressure-loaded regulator:
1. Install a shutoff valve in the pressure-loading
piping or tubing.
2. Connect the piping or tubing to the 1/4 NPT
c o n n e c t i o n i n t h e d i a p h r a g m a n g e ( k e y 2 , F i g u r e 8 ) .
If the loading regulator used with the pressure-
loaded 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
device. In all cases, check the pressure setting to
make sure it is correct for the application.
The maximum inlet pressure for a specic 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. Slowly open the upstream block valve.
4. If a bypass line is used, slowly close the bypass
line block valve.
5. To adjust the downstream pressure, follow the
appropriate procedure:
a. 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. refer to
the Instruction Manual of the pressure-
loading device for downstream pressure
adjustment procedures.

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. Tighten the Type 6492HM (or 6492HTM) safety
override pilot of the upstream valve all the way in
to its highest spring setting.
4. Tighten the Type 6392 pilot of the upstream valve
all the way in to its highest spring setting.
5. Tighten the Type 6392 pilot of the downstream
valve to the desired downstream pressure.
6.* Loosen the Type 6392 intermediate pilot on the
upstream valve to the desired intermediate
pressure (normally 50% of inlet pressure).
7. Loosen the Type 6492HM (or 6492HTM) safety
override pilot of the upstream valve until there is no
spring load.
8. Tighten the Type 6392 pilot of the downstream
valve all the way in to its highest spring setting.
9. Tighten the Type 6492HM (or 6492HTM) safety
override pilot of the upstream valve to desired
pressure as specied per ASME Boiler and
Pressure Vessel Code, section VIII.
10.* Loosen the Type 6392 pilot of the
downstream valve to the desired downstream
pressure setpoint.
To take the regulator out of operation:
1. If a bypass line is used, slowly open the
bypass line block valve while monitoring the
downstream pressure.
2. Close the upstream block valve.
3. close the
downstream block valve.
