Check valve
Check valves prevent backflow in a piping system, allowing the water to flow in one direction.
It permits unobstructed flow and automatically shuts as pressure decreases. The pressure of the fluid passing through a pipeline opens the valve, while any reversal of flow will close the valve to protect the piping and pumps. If the flow reverses and there is no check valve, water hammer can occur, so having a check valve can potentially prevent water hammer, back spin or upthrust by preventing any pressure surges. A check valve is recommended for a range of water applications and should be a vital component in all submersible pump installations.
Foot valve
Foot valves and check valves can be quite confusing as some foot valves can be used as check valves. A check valve is basically designed to stop water from going backwards and allows liquids to flow through it in only one direction, whereas a foot valve is for the use as an inlet of suction pipe and used to prime the pump. They are virtually the same, except a foot valve is at the bottom of a pipe (hence the name foot) and a check valve is usually just on top of the filter screens.Foot valve types
Foot valves are required to maintain optimum function of water in pumping systems. And with our vast range of foot valve types, we accommodate for a wide range of liquid types. We stock brass foot valves which are resilient and to the upmost quality, poly flanged foot valves; which can be used as either a check valve, foot valve or suction screen, and hydro- flo foot valves. Our hydro-flo acetal foot valves vary from 50mm- 10mm with a flow range of anywhere from 7.5L/s- 45L/s, whereas our hydro-flo stainless steel foot valves vary from 50mm- 200mm with a flow range from 40L/s- 150L/s.
