A check valve or one-way valve is a valve that allows fluid (liquid or gas) to flow through it in only one direction.

Check valve designs have evolved drastically over the last 20 years, and the aim of designers has revolved around increasing the speed of closure under its own power. In the case where pump control valves failure mode is not enough (Or no failure mode at all), a fast acting check valve can provide the solution. Different designs are available, listed below. If you need more information about check valves or want to know specifically what solutions you require, get in touch through our contact page.

Ball Check Valves

A ball check valve is a check valve in which the movable part to block the flow, is a spherical ball. In some ball check valves, the ball is spring-loaded to help keep it shut.

Nozzle Check Valves

The Nozzle check valve has become the most favoured Check Valve in terms of Water Hammer reduction and low headloss due to its Venturi “Nozzle” design.

Silent Check Valves

This valve design works on the “Axial Flow” principle where the flow is inline and with a high recovery factor and resultant low pressure drop.

Swing Check Valves

A swing check valve  is a check valve in which the disc swings on a hinge or trunnion,  either onto the seat to block reverse flow or off the seat to allow forward flow.

Tilting Disk Check Valves

This Check valve is popular on larger sizes where short Face to face dimension is important. This valve disc is seated at an angle which ensures a smaller travel angle of the disc and hence faster closing.
