Frequently Asked Questions
What is a foot valve and where is it installed? +
A foot valve is a non-return valve installed at the inlet of a pump suction line, usually at the submerged end of the pipe. Its job is to stop backflow when the pump stops and help keep the suction line primed.
Why does a foot valve include a strainer? +
The integrated strainer helps stop sand, debris, and other solid impurities from entering the pump. This protects the pump internals and reduces the risk of malfunction or premature wear.
Why is a foot valve important on pump suction lines? +
Without a foot valve, liquid in the suction line can drain back when the pump stops. That can lead to loss of prime, delayed restart, and extra stress on the pump. A foot valve helps the system restart more reliably.
Can a foot valve be used for isolation or throttling? +
No. A foot valve is intended for automatic non-return duty. It should not be selected as an isolation valve or for flow regulation and throttling.
What is the difference between the threaded and flanged foot valve versions? +
The threaded brass version suits smaller pipe sizes and compact installations. The flanged version covers larger sizes and adds spring-assisted silent closing with low head loss for industrial water duty.
When should a spring-assisted foot valve be preferred? +
A spring-assisted design is the stronger choice when you want faster closing, quieter operation, and better control of reverse-flow effects in larger industrial water systems.
