Thread Swing Check Valve

Thread Swing Check Valve is a specific type of Check Valve characterized by its threaded end connections.

It operates on the standard swing check principle: a disc (the "swing") inside the valve body pivots freely. Forward flow pushes the disc open; when flow ceases or reverses, the disc swings closed by gravity and backpressure to prevent reverse flow.As a professional industrial valve manufacturer, Wenzhou Chenyu Valve Co., Ltd. (Chenyu Valves) supplies high-quality Thread Swing Check Valves. These valves are built to relevant standards, offering reliable sealing and durability for preventing backflow in compact, threaded piping systems.
