Type 92B Pressure Reducing Valve and Type 92P Air-Loaded Pressure Reducing Valve

The Type 92B Pressure Reducing Valve (PRV) is the standard steam valve for the industry. It can withstand dirty operating environments while providing accurate and stable pressure control. The Type 92B steam valve is designed to provide decades of continuous service. The Type 92B steam valve is applied as a main pressure reducing valve in industrial process heating applications such as heat exchangers, evaporators, digesters, and reactors.

The Type 92B steam valve is rated for inlet pressure up to 300 psig (21 bar) and inlet temperatures of 600ºF (316ºC). Maximum controlled outlet pressure is 250 psig (17,2 bar). The air loaded, pilotless version of the Type 92B steam valve is the Type 92P steam valve . The Type 92P is air loaded using a Type 67CFR airset, a Type 670 panel loader, or a PID controller.

Type 92C Self-Powered Control Valve



The Type 92C regulator is a cost effective pressure reducing regulator used in steam service. This regulator is available with a Type 6392 pilot or without a pilot for use as a pressure-loaded regulator.

Type 92S Self-Powered Control Valve

The Type 92S pressure reducing control valves are piston actuated for high cycle steam service. The Type 92S control valves and pilot use lapped seating surfaces that have been proven to minimize seat leakage. The Types 6492H and 6492L pilots have bellows sealed stems to eliminate stem guide friction.

The steel and stainless steel Type 92S control valves are available with a set point range of up to 250 psig (17,24 bar) and a maximum temperature of 650 º F (343 º C).

The Type 92S control valves can be used as a working monitor by adding a second Type 6492 pilot. The intermediate pressure must be high enough to meet the minimum differential pressure requirement of the second regulator. Pilot supply for the second regulator can be connected to the upstream system. When intermediate pressure may be too low (minimum differential pressure is pilot supply pressure minus outlet pressure). 

Features

  • Good shutoff for low downstream buildup
