Check Valves
(4 products)
Non return valves are fittings for use on plumbing systems, relying on a pressure differential to work. They are designed to ensure fluid only flows one way to prevent backflow. Check valves are mainly used on systems where water is discharged, where a pump is fitted or to prevent water contamination. Available in double and single types, with a double type offering higher performance as it has two checks rather than just one.
