High Pressure Safety Valve HVAC: Description and Operation
A/C High Pressure Safety Valve
The A/C compressor pressure relief valve is located in the A/C manifold and tube.
An A/C compressor pressure relief valve has been incorporated in the compressor's 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.
After the excessive pressure has been relieved, the valve closes to prevent total refrigerant loss.
