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.


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.


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