Swing check valve 3D print model

A swing check valve is a type of non-return valve that allows fluid to flow in one direction only and automatically prevents backflow. It operates using a hinged disc or flap that swings open when fluid flows in the forward direction and swings closed when flow reverses, sealing against the valve seat. Swing check valves are commonly used in water, sewage, and process piping systems to protect pumps and other equipment from damage due to reverse flow. They are valued for their simple design, low pressure drop, and reliable operation in horizontal or vertical flow applications.
