Less Footvalves and Reflux Valves Foot valve is generally placed at the lower end of the suction pipe of a centrifugal pump to prevent the suction pipe from emptying while the pump is at rest. Consequently, when the pump is first started, it does not have to exhaust the air from the suction pipe. Reflux valves are generally fitted at the top end of the suction line or bore pipe of a centrifugal pump. Reflux valve has threaded portions at both the ends.
Valve body is made of cast iron and the flap is of quality rubber.
