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

Stop Check Valve is generally made use of for pipes that only allow the tool to stream in one instructions and also protect against the opposite circulation. Under the action of fluid stress moving in one direction, the valve disc opens. When the liquid streams in the contrary instructions, the shutoff disc acts upon the valve seat via the liquid stress and also the weight of the shutoff disc, thereby cutting off the circulation. It can be used to stop the medium from flowing back in various pipelines of the refrigeration system.
