Cartridge check valve CZFM series

stainless steelEPDMFKM

This threadless, cartridge-style, one-way valve is made with an elastomeric valve seat for improved checked direction leakage performance. The soft seat makes this check valve ideal for pneumatic applications where zero leakage is required or as a fill 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 - Lohm Rate: 250 Lohms - Maximum Working Pressure: 400 bar - Valve Seat Type: Elastomeric General Performance - Lohm Rate: 250 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.
