Differential Pressure Control Valve with Relief Function (Pilot)
Maintains stable differential pressure, protects pumps, allows pressure relief when required, reduces water hammer, improves system efficiency, and ensures safe, smooth operation in commercial and industrial water systems.
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, preventing pressure equalization.
