Manual Plastic Check Valve Options
Foot Valves (1/2" – 4")
A ball check valve with a foot screen can be installed vertically or horizontally on the suction side of a pumpp. The foot valve is an optional ball check valve arrangement where a screen is fitted into the inlet end of a ball check valve. This screen is used to filter large debris and solids from a fluid to prevent damage to pumps, clogging of valves and to protect downstream instrumentation. Foot valves can be typically found anywhere there is a check valve used as an intake. This includes pump inlets, lift stations and drains.
