Non-Slam Check Valves Swing Check Valves - Campbell Sevey
www.campbell-sevey.comOften called flapper style check valves, swing check valves are a more traditional variety. The disc of a swing check valve is secured to the body of the valve by a trunnion and hinge arm, without the aid of a spring. Unlike a non-slam check valve, which opens and closes at rates comparable to the pressure of the fluid flow, a swing check

SWING CHECK VALVES - BFE
www.bfe.itSWING CHECK VALVE DESCRIPTION Swing check valves, like all check valves, are used to prevent back flow in the line. The pressure of the fluid passing through a system opens the valve, while any reversal of flow will close the valve. The swing check valve functions by allowing flow forces to move the closure element, it is a
