High Pressure Safety Valve HVAC: Description and Operation
An A/C compressor pressure relief valve is incorporated in the compressor A/C manifold and tube to:
- Relieve unusually high refrigerant system discharge pressure buildups, (3103 kPa 450 psi and above).
- Prevent damage to the A/C compressor and other system components.
- Avoid total refrigerant loss by closing after the excessive pressure has been relieved.
