RS PRO is proud to introduce the BI range of single checks valves designed for use in water supplies. These high-quality valves are constructed from a DZR copper alloy and finished with nickel plating. Our check valves can be installed horizontally or vertically in pipework and offer rapid closure preventing flow reversal and hydraulic shock. Three sizes are available, each designed for use with water outlets such as a thermostatic shower or thermostatic taps.

If you install an additional single check valve in the same supply pipe, you create a non-verifiable double-check valve. This application will prevent backflow and contamination of the water supply.
