The disk swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when upstream flow is stopped, to prevent back-flow. The disc in a swing type Check valve is unguided as it fully opens or closes. There are many disk and seat designs available, in order to meet the requirements of different applications. The valve allows full,unobstructed flow and automatically closes as pressure decreases. These valves are fully closed when flow reaches zero, in order to prevent back-flow. Turbulence and pressure drop in the valve are very low.has simple in-field repair-ability to mitigate downtime.
