High Pressure Safety Valve HVAC: Description and Operation

PRESSURE RELIEF VALVE

This valve opens if the pressure of the high-pressure refrigerant gas rises to a dangerously high level to release part of refrigerant into the atmosphere, thus protecting the compressor. The valve is designed to limit the amount of released gas to the necessary minimum.

Valve opening pressure: 3.72 MPa (38 kgf/sq.cm)
Valve closing pressure: 1.8 MPa (17.5 kgf/sq.cm)
