Itap 1 1/2 Inch Check Foot Valve Female Suction Non Return Valve For Pumps Brass

Suitable for suction lines on top-offtake tanks (where an anti-siphon valve is not present). These valves are often used in dispensing pump systems, particularly with Centrifugal pumps, to prevent the pump from de-priming during rest. Suitable for use with water, Oil, Diesel, and many other none toxic fluids. The check valves are uni-directional; in the sense that they manage the flow in one direction only, which is indicated by the arrow on the body. The valves are composed by a spring, a little valve and a couple of parts made of brass (body and end-adapter) which contain them and that are assembled by means of threat and a sealed material to obtain their aim.
