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.
From plugs to solenoid valves, there’s a vast array of products that The Lee Company can offer. If you’d like to discuss the best solution for your specific application or to learn more about our capabilities, use-cases, or quality standards, contact your local Lee sales engineer.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
