Understanding Swing Check ValvesStructure and FunctionSwing check valves, also known as tilting-disc check valves, consist of a hinged disc that swings open to allow fluid flow in the forward direction and closes to prevent backflow. The disc is mounted on a hinge or trunnion, allowing it to pivot a
