Gas pressure relief valve CZFM series

airstainless steelEPDM

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. - Mounting Configuration: Insert - Into Metal - Diameter: 5.97 mm - Full Open Lohm Rate: 700 Lohms - Maximum Working Pressure: 400 bar - Relief Pressure Range: 100 to 400 kPa General Performance - Lohm Rate: 700 Lohms - Valve Flow Direction: Forward Flow - Cracking Pressure Definition: Is the uprun pressure at which the valve will flow more than 300 SCCM of air. - Checked Direction Leakage: Zero drops/minute on hydraulic fluid.
