Cartridge check valve COFM series

stainless steel

This threadless, cartridge-style restrictor check valve is 5.5 mm in diameter and is designed for installation into metal manifolds. Functionally, a restrictor check valve is an orifice in series with a check valve in one component to allow for metered flow in one direction and checked for the other. The valve’s locking end uses the field-proven Lee Controlled Expansion Principle to provide secure retention without the need for threads, O-rings, or sealants. Featuring an all-stainless steel design with a high-quality metal seat, this valve offers low leakage, repeatable cracking pressures, and long life. It is 100% tested to ensure performance. - Mounting Configuration: Insert - Into Metal - Diameter: 5.47 mm - Metered Flow Range: 400 to 40,000 Lohms - Maximum Working Pressure: 280 bar General Performance - Metered Flow Lohm Rate Tolerance: ± 5% - Cracking Pressure: 40 ±30 kPa (6 ±4.4 psid) - Cracking Pressure Definition: Is the uprun pressure at which the valve will flow more than 50 SCCM of air - Leakage: 20 SCCM (max.) at 172 kPa (25 psid) on Air - Maximum Working Pressure, Checked Direction: 280 Bar - Maximum Working Pressure Differential, Flow Direction: 40 Bar - Installation Force: 625 kgf (max.)
