Swing check valve

Our company is at the top place in all over the India for manufacturing the great ranges of swing check valves. A swing check valve is a butterfly-style check valve in which the disc, the movable part to block the flow, swings on a hinge or grunion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the center line between the two ports or at an angle. Although swing check valves can come in various sizes, large check valves are often swing check valves. Swing check valve shut off depends on gravity and reverse flow. The pivot point of the swing check valve is outside the edge of the disc and, the greater the head, the greater the possibility that the fluid will flow back through the valve before the disc can shut off. To affect complete shut off, the disc of a swing check valve must travel through a 90 angle arc to the swing check valve seat.

For standard or critical applications our swing check valves offer a wide range of convenience, performance and safety options. Full opening designs minimize pressure drop across the valve.

An important thing to be aware of when installing a swing check valve is that it is not completely maintenance free since the disc needs to be cleaned once in a while. Furthermore, a lever is often mounted to enable visual check. Therefore, swing check valves are often installed where personnel is present.
