Pilot Operated Valve - Prevention of Pressure Equalization

Pilot Operated Valve - Prevention of Pressure Equalization

Model Numbers: SWV-PR11/12/22


SWV-PR11,12,22 (Prevention of Pressure Equalization):


Differential pressure pilot valve and relief pilot valve are installed on the main valve to maintain the outlet side pressure below the set level regardless of pressure changes in the inlet side.  Even when abnormal pressure change occurs within the piping system and causes the outlet side pressure to rise above the set level, the attached relief pilot valve can effectively relieve the pressure as needed.
