Performance Feature
Check valve automatically opens and closes the valve flap depending on the flow of the medium itself, allowing the medium to flow in one direction, and plays an important role in protecting pipeline machinery and equipment from damage by water hammer. During the working process of the check valve, the instantaneous impact pressure ΔH of the water hammer may be several times higher than the normal working pressure, which has a great influence on the performance stability and working reliability of the system. The problem of water hammer is more prominent. In order to prevent the hidden danger of water hammer in the pipeline, some new structures and new materials are used in the design of the check valve to ensure the working characteristics of the check valve and to minimize the impact of the water hammer.

Application
With different materials, butterfly check valves can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
