Type 92C

Installation

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 Specications 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 qualied 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.

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 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.

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.
