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
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 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 pilot-
operated 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.
