Silent Check Valve

Silent check valve, valve flap sliding along the centerline of the valve body. Pipe-type check valve is a new kind of valve, its small size, light weight, good processing technology, is one of the development direction of the check valve. But the fluid resistance coefficient is slightly larger than the swing check valve. The role of the Silent check valve is to prevent the flow in the opposite direction, only allows the medium to flow in one direction. Usually this valve is automatic, in a direction of flow of fluid pressure, valve open; fluid flow in the opposite direction, by the fluid pressure and the valve flap of the self-gravity of the valve flap on the valve seat, thus cutting off the flow. Not suitable for use in media containing solid particles and viscosity.
