Compressor Relief 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.
