High Pressure Safety Valve HVAC: Description and Operation

A/C COMPRESSOR PRESSURE RELIEF VALVE

An A/C compressor pressure relief valve is incorporated in the compressor manifold and tube assembly (4.0L) or the A/C compressor (4.6L or 5.4L) to prevent damage to the A/C compressor and other system components, and to avoid total refrigerant loss by relieving unusually high refrigerant system discharge pressure buildups.
