Part Details | SYSTEM PRESSURE REGULATING VALVE
4820-01-554-2927 A value designed to automatically maintain within close limits a predetermined pressure within a closed system regardless of the higher fluctuating or constant inlet pressure. The excess pressure is by-passed to the accumulator or reservoir in lieu of passing through the entire system. It is designed primarily for use in refrigeration and air conditioning systems. Excludes VALVE, REGULATING, FLUID PRESSURE and VALVE, CALIBRATED FLOW.
