IMH 855 LC2 Series Pressure Relief Valves are 8 mm diameter threadless, cartridge-style valves that offer higher flow capacity. The 855 LC2 Series offers more than a 165% increase in flow capacity over our standard 855 series forward flow pressure relief valve product line. These valves also utilize The Lee Company’s field-proven insert principle that provides secure retention without the need for threads, O-rings or sealants and are designed for installation into metal manifolds. The valves are all stainless steel construction with a high-quality metal to metal seat providing low leakage and long life. The valves guided ball design ensures fast response, low hysteresis and highly repeatable cracking pressures.
