Check Valves, also known as non-return valves, allow fluid flow in one direction while preventing backflow in the opposite direction.
Check valves are wildly used to prevent backflow, protect pumps and compressors, control flow direction, ensure water supply safety in plumbing systems, and maintain efficiency in various fluid based applications.
