Pressure relief valve<br />

Pressure relief valve is installed on A/C compressor or<br />

receiver.<br />

At a pressure of approx. 38 bar positive pressure, valve<br />

opens and closes again once pressure has dissipated<br />

(approx. 30 bar).<br />

Refrigerant does not escape completely.<br />

Depending on the version, a transparent plastic disc may<br />

be installed which breaks off as soon as the valve is<br />

activated.<br />
