Wafer Check Valve Without Flange With 125 Diameter (221011259)

Wafer Check Valve Without Flange With 125 Diameter (221011259) are in-line piping valves used to control fluid flow direction and reduce or fully prevent possible back flow within plumbing systems. Wafer check valves are also known as clack valves, reflux valves, non return valves and one way valves. The valve must be installed with the flow arrow on the tag pointing to the flow of water. Three diameters of straight pipe upstream of the valve are recommended to prevent turbulent flow thru the valve, which will cause vibration and wear. Valves must be mounted between ANSI B16.
