Gas pressure relief valve CZPM series

airstainless steelEPDM

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 it 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. - Mounting Configuration: Press-In - Into Plastic - Diameter: 5.94 mm - Full Open Lohm Rate: 700 Lohms - Maximum Working Pressure: Dependent on Housing Material - Relief Pressure Range: 100 to 400 kPa General Performance - Lohm Rate: 700 Lohms - 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.
