DIN Swing Check Valve

A DIN swing check valve is a type of valve that allows fluid to flow in only one direction while preventing backflow. It consists of a hinged disc that swings open in the direction of flow and closes when the flow reverses. The valve is designed to comply with the German standard DIN, which specifies the dimensions, materials, and testing requirements for industrial components. DIN swing check valves are commonly used in water, oil, gas, and chemical applications where backflow prevention is critical.
