Discharge Valve Discharge valves are mainly used for discharging material from the bottom of storage tanks, reactors and other vessels. The valve is connected to the equipment and is located at the bottom by flanging or butt-welding to eliminate the residual phenomenon of process media usually at the outlet of the vessel. According to the needs of the actual situation, it is divided into upward display type and downward display type. The upward type is used for kettle discharge with a stirring discharge valve; the downward type is used for kettle discharge from frame-anchored stirrers.
