Check Valves

A check valve (also referred to as clack valve, non-return valve or reflux valve) is a self-acting device that prevents the reserve flow of process media within a pipeline.  Valves should be selected taking into consideration process media, pressure and velocity. 

Our range of check valves includes an extensive range of swing, wafer, axial, ball, non-slam recoil and backflow preventer check valves for use in potable, clean and wastewater applications.

Check Valves

 

Our UK designed swing check valve range has undergone stringent independent testing and certification by the Water Regulations Advisory Scheme (WRAS) to demonstrate compliance to the Water Supply (Water Fittings) Regulations and Scottish Water Byelaws.  Under the approval, our swing check valves may be installed either horizontally or vertically and available with an optional external weighted arm.

While our UK assembled self-cleaning Ballbrake® ball check valve is certified to EN12050-4.  Available with either threaded or flanged connections, full-bore and suited to wastewater applications.

 

Our Check Valve Design

As experts in this field for many years, we have worked with some of the leading names in the industry to design a swing check valve that exceeds expectations. Our valves are a self-acting valve that uses a hinged disc, and when placed in the pipeline, it prevents the backflow of water and reverse flow.
