97170 Double Port Pressure Regulator

• Direct Drive Actuation
• One Valve for Upstream or Downstream Control of Low Pressure Gas Lines
• Float and Liquid Design for Greater Sensitivity
• Fewer Moving Parts for Longer Service Life
• No External Power Source Required

The S&J Biogas 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 -0.4" to -0.1" and an optional -0.5" to 1.5" range for higher pressures. The standard for a flanged aluminum body is 2" to 8" with SS 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 Biogas 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.

The 97170 is 100% U.S. made.
