The Type 92C regulator (Figure 1) is an economical

cast iron, steel, or stainless steel pressure-reducing

regulator used in steam, liquid or hot air service. This

regulator is available with a Type 6392 pilot for use

as a pilot-operated regulator 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 Type 67, 1301F

regulator, or a 670 panel loader can 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.
