Counter-clip silent check valve

Short Description:

The valve that relies on medium flow and force to open or close by itself to prevent medium backflow is called check valve, also known as check valve, one-way valve, counterflow valve, and back pressure valve. Check valve is an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and release of container medium. The double-lobe check valve is used for pure pipeline and industrial, environmental protection, water treatment, water supply and drainage pipelines of high-rise buildings to prevent reverse flow of media. The check valve adopts a pair of clamps, the butterfly plate is two semicircles, and the spring is forced to reset. The sealing surface can be surfacing wear-resistant material or lining rubber for the body. It has a wide range of applications and reliable sealing. Check valves belong to automatic valves. They are mainly used in pipelines where media flow in one direction. Only one direction is allowed to flow in order to prevent accidents. Usually, the valve operates automatically, and the disc opens under the action of a fluid pressure flowing in one direction. When the fluid flows in the opposite direction, the disc acts on the seat by the fluid pressure and the self-coincidence disc of the disc, thus cutting off the flow.
