1. Products Introduction
PVC Single Union Swing check valve is the action of allowing the flow of the medium itself to drive the valve flap to open and close. It is generally a valve that prevents the backflow of the medium, so it is also called a back-pressure valve, one-way valve, clapet non-return flap valve, etc. It is mainly used to prevent the backflow of the medium or the discharge of the medium in piping system. Usually, this kind of valve works automatically. Under the pressure of the medium flowing in one direction, the valve flap can automatically open. If the medium flows in the wrong way, the pressure and the valve flap act on the valve seat, which can cut off the flow. Sanking's PVC single union Swing Check valve is flap type, even if there is only a drop of water/fluid backflow, the valve will be closed. Compared with the hemispherical structure, there is no any reversed pressure requirement, more safety and reliability. It can be installed horizontally or vertically.
Sanking team believe that in the industrial pipeline system, the industrial pipeline as the carrier of his blood flow, must ensure its stability and ease of operation. PVC single union swing check valve is providing with union in one side, and its flap is made by PVDF as standard. It further ensures that the valves are easy to operate and long-term life, bring the best experience and the greatest guarantee to the end-users.
