Angle valve description DOFUN check valve series products are mainly used in pipelines that only allow the medium to flow in one direction and prevent reverse flow. Under the action of the fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the valve disc acts on the valve seat under the action of the fluid pressure and the weight of the valve disc, thereby cutting off the flow
