The PVC Single Union Swing Check Valve is a self-operating valve that opens and closes as a result of the medium's flow. It is commonly used to prevent backflow, often referred to as a back-pressure valve, one-way valve, or non-return valve. This valve works automatically by opening under the pressure of flow in one direction. If the flow reverses, the valve flap seals against the valve seat to prevent backflow. Sanking's PVC Single Union Swing Check Valve closes even with minimal fluid backflow, ensuring safety and reliability without requiring any reversed pressure. It can be installed either horizontally or vertically.

At Sanking, we believe that the pipeline system is essential for the stability and smooth operation of industrial processes. The PVC Single Union Swing Check Valve includes a union on one side, and its flap is made from PVDF as standard. This ensures both ease of operation and long service life, offering the best experience and maximum reliability for end users.
