I. Product Overview


Bottom discharge valves are primarily used in operations at the bottom of reactors, storage tanks, and other containers. They are welded to the bottom of tanks via a bottom flange, effectively eliminating the residue issue of process medium at the container outlet. According to actual operating conditions, the bottom discharge structure is designed as a flat-bottom type, with the valve body in a V-shape, featuring both lifting and lowering valve disc operation modes.


The valve body cavity is equipped with abrasion and corrosion-resistant seals, which can protect the valve body from medium erosion and corrosion at the moment of valve opening. Additionally, the seals are treated specially to achieve a surface hardness of HRC56 - 62, offering high wear and corrosion resistance. The valve disc sealing is customized to the need, with all covers being surfacing welded with hard alloys. The sealing pair employs a linear seal form, ensuring reliable sealing while effectively preventing scab formation. Moreover, a short-travel valve disc design is adopted to further enhance valve performance. This valve is widely used in numerous industries such as chemicals, petroleum, metallurgy, pharmaceuticals, pesticides, dyes, food processing, and offers various operation methods including manual, pneumatic (spring return, double-acting, with and without a handwheel), electric, hydraulic, and gear.

II. Product Features


  1. User-friendly and versatileEasy to operate, offering freedom and agility, reliable movement, and effortlessly adapts to frequent operation demands across various work scenarios.

  2. Simple repair and replacementThe valve disc assembly and maintenance are simple, the sealing structure design is reasonable, the sealing ring replacement is convenient and practical, significantly reducing the cost and difficulty of later maintenance.

  3. Unique structural designFlat-bottomed discharge structure and V-shaped valve body design, effectively enhancing discharge efficiency and reducing material residue. The short-travel valve disc design optimizes the overall performance of the valve, making it more responsive.

  4. Outstanding sealing performanceThe valve body cavity seal is treated for high wear resistance and corrosion resistance. The valve disc is sealed with hard alloy using a linear sealing method, ensuring excellent sealing performance and preventing medium leakage and scaling.


Section 3: Operation Method Instructions


  1. Manual operationThe valve is opened and closed by rotating the handwheel. Clockwise rotation closes the valve; for downward-tilting valves, the valve stem rotates downward; for upward-tilting valves, the valve stem moves upward.

  2. Pneumatic operationAvailable in spring return, double-acting, and various configurations with or without handwheels, these valves can be flexibly selected based on actual control requirements and site conditions. They are powered by compressed air to achieve automated control.

  3. Electric OperationUtilizing an electric motor as the power source, the valve's opening and closing degrees are precisely controlled through an electrical control system, suitable for remote control and highly automated production processes.

  4. Hydraulic operationPowered by a hydraulic system, it generates significant driving force, suitable for applications requiring high precision in valve operation, ensuring stable and reliable valve performance.

  5. Gear operationBy means of a gear transmission mechanism, the operating force is amplified or converted, achieving smooth control of the valve, particularly suitable for large valves requiring a high torque.


The downstream ball valve offers an efficient and reliable solution for material discharge across various industries, thanks to its exceptional performance, diverse operation methods, and convenient maintenance features.
