Swing Check Valve

SVR Global is a leading Swing Check Valve Manufacturer in the USA. A swing check valve is a valve that allows and stops liquid stream. It stops any medium going through from streaming in reverse. It operates on the principle of a swinging disc or flap that is hinged at the top inside the valve body. When there is backflow, the disc swings back to the closed position, preventing reverse flow.

Design:

The swing check valve consists of a valve body, seat, and disc linked to the hinge. Upon encountering a specified flow rate, the disc rotates to a horizontal position, enabling forward flow. It returns to the valve seat when the flow stops to prevent backflow. Depending on the valve size, check valves require a certain amount of flow rate to achieve stable operation. Therefore they should be sized to determine suitability for the service conditions.

Overview Key Features of Swing Check Valve

● Swing check valves come with different body end configurations, such as flanged ends, butt-weld ends, or threaded ends, depending on the installation requirements.
● The valve body is typically made of materials such as cast iron, cast steel, stainless steel, or other alloys. The body houses the internal components and provides a connection point for the pipeline.
● Swing check valves are sensitive to the orientation of installation. They should be installed in a way that allows the disc to swing freely against gravity.

Industries:

Swing Check Valve are used where backflow prevention is essential including water and wastewater treatment, HVAC systems
● Chemical Industry.
● Water control frameworks.
● Petroleum Industry.
● Oil Industry.
