About – CHECK VALVES

Sunshine Metal Industries is a top manufacturer, supplier, and exporter of Swing Check Valves from India. A swing check valve, or tilting disc check valve, is a type of check valve where the disc, the movable part that blocks the flow, swings on a hinge either onto the seat to block reverse flow or off the seat to allow forward flow. Sunshine Metal Industries’ swing check valves are crafted from high-quality materials, ensuring the highest precision and performance.

It is used to stop piping and prevent backflow. Backflow occurs when the substance in the pipe flows in the opposite direction when the valve is closed. There are several types of these valves, including ball check valves, stop-check valves, cone check valves, and disc check valves, among others.

The principal category is the most common one. A ball in the shell of the valve fits firmly against the side of the valve where the water comes in. Water pushing through the pipe moves the ball against the spring, permitting water through the valve. When the water is stopped, the ball is pushed into place by the spring and shields water from flowing in reverse through the pipe.

The second kind is an item with override control to stop flow regardless of flow direction or pressure. It can not only shut in response to backflow or inadequate forward pressure but can also be intentionally closed by an external mechanism, thus stopping any flow regardless of forward pressure.

The third type is similar to ball check valves, but the fitting that seals the valve is shaped like a cone. It is also known as a lift check valve, where the disk, usually referred to as a lift, can be lifted off its seat by higher pressure of the inlet or upstream liquid to allow flow to the outlet or downstream side. The cone is suspended on a bar, enabling it to lift out of the way when water is flowing and drop back into place when the water is off. If water backflows through the pipe, it pushes against the cone, creating a seal that prevents further flow.
