558 LC Series Press-in Pressure Relief Valve

IMH 558 LC Series Press-in Pressure Relief Valves are 5.5 mm diameter cartridge-style valves that offer higher flow capacity. The 558 LC Series offers more than a 78% increase in flow capacity over our standard 5.5 mm CCPI series pressure relief valve product line. These valves are specifically designed for installation into plastic housings and fittings. Their unique barbed design provides easy “press-in” installation ensuring retention and prevents any by-pass leakage around the valve. The valves all stainless steel construction provides compatibility with a wide range of fluids and gases. A high quality metal to metal seat provides low leakage and long life. The valves guided ball design ensures fast response, low hysteresis and highly repeatable cracking pressures.
