Duckbill check valve CKV38-.-.-..

UNFmale-malehexagonal

The CKV38 series check valve permits free flow in one direction and no (checked) flow in the opposite direction. The valve is specified in many applications because of its very low cracking pressure (typically less than 0.5 psig), its excellent repeatability, and leak-tight operation. Approximate Weight: 9g in stainless steel (303 & 316) Note: Check valve elements are designed for regular use. If the valve is not used for an extended period of time, the duckbill element may stick upon first use, resulting in a one-time higher cracking pressure requirement. Features Duckbill checking element allows for cracking pressures around 0.5 psig. Check valve elements are typically actuated by reverse pressure and are best suited for applications with over 5 psig of back pressure. If the valve is required to check with minimal back pressure, contact a Beswick applications engineer to discuss available options.
