Flange check valve is used in fluid pipeline system, which relies on the flow of the medium in the pipeline itself to generate power, and automatically open and close, can be used to prevent the medium in the pipeline backflow, to prevent the pump and its driving motor reversal, as well as containers of media discharge. Flange check valve flap was disc-shaped, rotating around the valve seat channel axis for rotary motion, because the valve channel into a streamlined, flow resistance than the rise of butterfly check valve small, suitable for low flow rate and flow of infrequent changes in large caliber occasions, but should not be used for pulsating flow, and its sealing performance is not as good as the lifting type.
