What is check valve?
The valve whose opening and closing parts open or close by the force of medium flow to prevent medium backflow is called check valve. The check valve is an automatic valve, which is mainly used on the pipeline with one-way flow of medium. The medium is only allowed to flow in one direction to prevent accidents.Usually, this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat, so as to cut off the flow.
