Spring –Loaded Check Valve

DN:50-2000 mm | PN: 6-40 bar

This valve is used during thrust or suction stroke of the pump to keep the space behind or front of the pump full of fluid and thereby assist in its operation. It is also used in pipes connected to secondary systems, such as branches, whose pressure may be higher than the main system, to prevent fluid from entering the secondary system into the main system. The check valve should open easily against the upstream flow and have a low head loss in the fully open position. Also, when closing it should not cause an in appropriate water hammer against the reverse flow.
