Non Return Valves

Non-return valves, also known as check valves or one-way valves, are a type of valve designed to allow fluid to flow in one direction only. They prevent backflow or reverse flow of fluid in a pipeline, which can cause damage to equipment, contamination of the fluid, or loss of system pressure. A non-return valve typically consists of a disc or ball that is held in place by a spring or other mechanism. When fluid flows in the desired direction, the disc or ball is pushed aside, allowing the fluid to pass through the valve.
