PPHSwing Check ValveIs a kind of automatic valve, mainly used to prevent the medium backflow, to ensure that the medium can only flow in one direction. Its working principle is to rely on the positive flow of the medium to push the valve open, when the medium flows backwards, the valve closes under the action of fluid pressure and self-weight, thus cutting off the flow. It is characterized by green environmental protection, acid and alkali corrosion resistance, light weight, good sealing, smooth inner wall, small friction coefficient and high conveying efficiency. Widely used in pure water and raw drinking water piping system, drainage and sewage piping system, salt water and seawater piping system, acid and alkali and chemical solution system and many other industries.
