Volkswagen Golf Service & Repair Manual: High-pressure safety valve

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.
