Butterfly check valve only allows the medium to flow in one direction and prevents the medium from flowing back. 
Usually butterfly check 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, thus cutting off the flow.
