IMH 558 Series Pressure Relief Valves are 5.5mm diameter threadless, cartridge-style valves designed for installation into metal manifolds. The valves use The Lee Company’s field-proven insert principle that provides secure retention without the need for threads, O-rings or sealants. 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.

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.
