The Chemtrol® True Union ball check valve stops the flow of media in one direction while allowing flow in the opposite direction, the valve with this chatter while maintaining pump prime. Ball supported by a system of guide ribs to give full flow with minimum turbulence and chatter. Equally effective in checking backflow from head pressure on the discharge or suction side of the pump. Use this with a 18291 PVC Check Valve to convert to a foot valve. Convert to a foot valve by replacing the inlet end connection on the valve with this foot valve screen assembly.
