The RS PRO PN63 check valves are a specific type of check valve designed for controlling the flow of fluids in a pipeline system. These vertical in-line spring check valves are manufactured according to the specifications of the PN63 pressure rating, indicating their ability to manage pressures up to 63 bars (or 6300 kilopascals).
Overall, PN63 check valves are reliable and robust devices that contribute to the smooth and safe operation of various fluid managing systems, ensuring the desired flow direction while preventing backflow.
Available in 1/4in, 1/ 2in & 3 /8 nominal pipe sizes, designed to fit into appropriate pipeline diameters.

Check valves play a crucial role in ensuring fluid flow in a single direction and preventing backflow, thereby protecting pumps, compressors, and other equipment from potential damage. They allow fluid to flow freely in one direction while automatically closing to prevent reverse flow.
