This threadless, 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 it ideal for pneumatic applications where zero leakage is required or as a safety relief valve for gas systems. This valve features The Lee Company’s field-proven locking end that provides retention into metal manifolds without the use of threads, O-rings, or sealants. 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.
