VARTE NON RETURN VALVE 1/2" FLAP TYPE

A non-return valve, also known as a check valve or one-way valve, is a type of valve that allows fluid flow in one direction while preventing reverse flow. It is designed to automatically open and close based on the direction of fluid flow, ensuring that the flow can only occur in the desired direction.

The operation of a non-return valve is relatively simple. When the fluid flows in the desired direction, the pressure pushes the valve disc or flap open, allowing the fluid to pass through. Once the flow stops or reverses, the pressure on the disc or flap decreases, and the spring (if present) helps to close the valve. This closure prevents any backflow or reverse flow of the fluid.

Non-return valves are commonly used in various applications to prevent backflow and maintain the desired direction of fluid flow. They are used in plumbing systems, water supply networks, pumping systems, and other fluid handling systems. Non-return valves help to protect pumps and equipment from damage caused by reverse flow and maintain the efficiency of the overall system.
