The flange swing check valve operates using a hinged disc that swings on a pivot. When fluid flows in the designated forward direction, the disc opens, allowing passage. Conversely, if the flow direction reverses, the disc swings shut, thereby sealing off the flow and preventing potential damage to the system. This functionality makes it an ideal choice for a range of applications, from water supply systems to industrial processes.
