High Quality In-Line Check Valve - JFlow 6833

Posted by

An ”’ inline check valve”’ is a check valve similar to the lift check valve. However, this valve generally has a spring that will ‘lift’ when there is pressure on the upstream side of the valve. The pressure needed on the upstream side of the valve to overcome the spring tension is called the ‘cracking pressure’. When the pressure going through the valve goes below the cracking pressure, the spring will close the valve to prevent back-flow in the process.
