The upward sliding discharge valve is a valve that opens when the valve disc moves upward. When opening, the valve needs to overcome the force of the medium, and the opening torque is greater than the closing torque; The downward sliding and plunger type discharge valves open with the valve disc moving downwards. When opened, the direction of movement is the same as the medium force, so the opening torque is smaller than the closing torque. Although there are significant differences between upward and downward discharge valves, their common feature is the close distance between the valve seat and the end face flange, less material retention, compact structure, and superior sealing performance. They are used in reaction pots in the fine chemical, pharmaceutical, and chemical industries, as well as in the transportation of fine and soft particle media
