The ASME B16.10 Swing Check Valve is a check valve designed in accordance with the ASME B16.10 standard, which specifies the face-to-face and end-to-end dimensions of straightway valves and the center-to-face and center-to-end dimensions of angle valves. This standard ensures installation interchangeability for valves of specific material, type, size, rating class, and end connection. The swing check valve features a hinged disc or "swing" that allows fluid to flow in one direction while preventing backflow. It is commonly employed in pipelines to ensure unidirectional flow, preventing reverse flow and providing crucial protection for pumps and other equipment.
