The high-pressure safety valve is fitted to the air conditioner compressor or the receiver. The valve opens at a pressure above approx. 38 bar and closes again when the pressure has dropped (approx. 30 bar).

Not all the refrigerant is lost from the system.

Depending on the version, a transparent plastic disc may be fitted, which breaks when the valve opens.
