High Pressure Safety Valve HVAC: Description and Operation
The pressure relief valve is mounted on the compressor. At approx. 38 bar (551 psi), the valve opens to vent excessive pressure. When system
pressure is reduced to approx. 30-35 bar (435-508 psi), the valve closes to prevent total refrigerant loss.
