ValveMan Brand VM6800 In-Line Check Valve- Product Overview

Dec 17, 2011

An ”’in-line 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.

ValveMan recently worked with a manufacturer of compressors. Several hundred ValveMan Brand VM6800 In-Line Check Valves 800 WOG offered the ideal solution. These valves are 316 stainless steel, feature an in-line design and include 2 piece and 3 piece configurations. It has a soft seat for bubble-tight shutoff and spring loaded.
