Swing Check Valves are the most common in the market. They have a straight-body design or a Y-pattern.This style of valve uses a disc-shaped flapper attached to a hinge to regulate flow. Forward flow in the valve causes the flapper to rotate and open the Valve. A reversed flow causes the flapper to rotate back to rest against the seat and close the valve.A butterfly-type valve has a disk that swings on a hinge-like apparatus to stop the flow. Large check valves are often this type. The disk is heavy, which causes damage over time to the seat as it closes, making it a higher-maintenance item.
