Pressure relief valve
The pressure relief valve is mounted on the compressor or the receiver drier. At pressures above 40 bar (580 psi), the pressure relief valve opens to vent
excessive pressure. When the system pressure is reduced, the valve closes to prevent total refrigerant loss.
A cap on the pressure relief valve will pop out if the valve has opened.
