Legend Valve® T-311 Cast Iron Swing Check Valve, 6" Flanged

Check valves are mechanical valves that permit gases and liquids to flow in only one direction, preventing flow from reversing. They are classified as one-way directional valves. Fluid/gas flow in the desired direction opens the valve, while backflow forces the valve closed

Aswing valvehas a disc, the movable part, which blocks the flow as it swings on a hinge or a trunnion , either onto the seat to block reverse flow or off the seat to allow forward flow.
