558 Series Press-In Pressure Relief Valve

The 5.5mm CCPI Series Press-in Pressure Relief Valves are cartridge style valves specifically designed for installation into plastic housings and fittings or soft tubing. Their unique barbed design provides easy “press-in” installation ensuring retention and prevents any by-pass leakage around the valve. These valves are 5.5 mm in diameter and contain all stainless steel construction providing compatibility with a wide range of fluids and gases. A high quality metal seat provides low leakage and long life. The valves guided ball design ensures fast response, low hysteresis and highly repeatable cracking pressures. The 5.5 mm CCPI Series pressure relief valve is available in models which utilize a ceramic ball for improved compatability with agressive fluids.
