97170 Double Port Pressure Regulator

The S&J 97170 Double Port Pressure Regulator maintains a constant upstream or downstream pressure in gas blanketing, vapor recovery and other similar gas systems. The Regulator is a double port, direct drive, float actuated valve.

Simple weights provide a factory calibrated set point with the standard range being from minus 0.4” to minus 0.1” and an optional minus 0.5” to 1.5” range for higher pressures. The standard for a flanged aluminum body is 2” to 8” with Stainless Steel pallets. An optional 1” NPT connection is also available. A large diameter float provides greater sensitivity with reduced line bounce. A reliable control protects valuable equipment. There are also no linkages to corrode, bind or develop friction.

The valve can be configured as a back pressure regulator to provide a reliable gas flow or as a pressure reducing regulator which will maintain a constant downstream pressure.

Its aluminum and stainless steel components withstand the severest of process environments. The S&J 97170 is especially designed for hydrogen sulfide and hot, wet methane which are the main components of digester gas streams in municipal waste water treatment facilities.
