This cartridge-style, safety pressure relief valve is made with an elastomeric valve seat for improved checked direction leakage performance. The soft seat on this 6 mm diameter relief valve makes ideal for pneumatic applications where zero leakage is required or as a safety relief valve for gas systems. This valve is designed specifically for installation into plastic housings, fittings, or soft tubing. It can be installed in either direction, providing forward or reverse flow capabilities. The valve is 100% performance tested.

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.
