Non Return Valve

Non-return valve is a mechanical component installed in a pipeline or system to ensure one-way flow of liquids or gases. It automatically opens when fluid flows in the intended direction and closes when the flow stops or tries to reverse, preventing backflow. The valve operates without manual control, using internal mechanisms such as a spring-loaded disc, ball, or flap that responds to pressure changes. When forward pressure is applied, the valve opens; when pressure drops or reverses, it shuts tightly to block reverse movement. Non-return valves are typically made from durable materials like brass, stainless steel, or plastic, depending on the application. They are widely used in water systems, air compressors, pumps, and car wash equipment to protect machinery, maintain pressure, and prevent contamination or damage caused by reverse
