South American valve is a top Swing Check valve supplier in Colombia. A Swing check valve is designed with a disc that swings on a hinge or shaft. This unique construction allows the disc to swing away from the seat, permitting forward flow. When the flow stops, the disc swings back and rests on the seat, effectively blocking reverse flow. The swing check valve functions based on the straightforward idea that fluid flow causes a hinged disc or flap to open and close. The fluid's pressure pushes the disc off its seat when it flows forward, as intended, enabling the fluid to pass through the valve. The hinge mechanism allows the disc to swing freely, facilitating this movement.

Under the action of gravity and the pressure differential across the valve, the disc swings back to its closed position when the flow ceases or reverses (backflow). The disc then presses up against the seat or valve body to stop fluid from returning through the valve. A swing check valve's primary function is to guarantee that fluid flows through a pipeline or other plumbing system only in one direction. Swing check valves help preserve system efficiency and shield equipment from backflow-related damage by allowing fluid to flow freely in one direction while automatically closing to prevent reverse flow. They are especially helpful in situations when it's imperative to prevent backflow, like water distribution systems, HVAC systems, and different industrial operations.

Main Features of our Swing check valves:

● The bonnet/disc design of this valve provides convenient access for maintenance purposes.

● The disc features a steel insert that is fully vulcanized with EPDM rubber, ensuring excellent sealing capability, especially for sizes up to DN 300. A lip seal on the disc further enhances tightness.

● The lightweight disc requires minimal force for opening and closing the valve. It is designed to move slightly both horizontally and vertically to achieve a completely tight closure.

● The hinge is tightened around the shaft with bolts to eliminate play, ensuring durability. Additionally, the valve's full bore design ensures low head loss during operation.

The shut-off characteristics of the valve are influenced by factors such as the weight of the disc and the force exerted by the return flow. South American valve is a reputed Swing Check valve supplier in Colombia. These factors contribute to the valve's ability to effectively control the direction of flow, making swing check valves ideal for applications where preventing backflow is crucial.
