Stainless Steel sanitary aseptic type Zero Dead Leg Tank Discharge Bottom valve
 
TheStainless Steel sanitary aseptic type Zero Dead Leg Tank Discharge Bottom valve with drain valve is a dedicated valve for sanitary fluid pipelines, aseptic type bottom valve suitable for bottom installation in various storage tanks. Its core function is to discharge, shut off, and perform sludge removal and cleaning operations on the tank bottom, achieving zero-residue control of the medium. Connection methods include quick-connect, welding, and flange type; the actuation method can be selected manually, pneumatically, or electrically, adapting to sanitary production conditions in industries such as food sanitary tank bottom valve and pharmaceuticals,meeting CIP/SIP cleaning and sterilization requirements, and ensuring aseptic cleanliness of the pipeline.
Similar products mainly include sanitary tank bottom diaphragm valves, sanitary tank bottom ball valves, ordinary tank bottom valves without drain, and sanitary discharge valves. TheStainless Steel sanitary aseptic type Zero Dead Leg Tank Discharge Bottom valvewith a drain valve adopts an integrated structure with its own drain channel, eliminating the need for additional piping. It can directly complete residual liquid drainage and cleaning, with no dead corners, meeting the high hygiene requirements of food and pharmaceutical industries. Compared to diaphragm valves, it has a smoother flow path, is more resistant to erosion, and has a longer service life; compared to ordinary tank bottom valves, it drains more thoroughly and is easier to maintain; compared to discharge valves, it is more compact in installation and more direct in operation, combining both discharge and drain functions. Its stable structure and strong sealing performance significantly improve production hygiene and efficiency, making it suitable for various sanitary operating conditions. sanitary-grade manual tank bottom valve with drain valve adopts an integrated molded tank bottom sealing structure, which allows for precise manual operation and comes with a quick drain interface. It meets FDA and 3A standards. Compared with similar domestic products, it has more reliable sealing, more convenient draining, and is cost-effective and flexible in customization. Compared with imported products, the delivery cycle is shortened by 50%, and the after-sales response is more timely.
 
TheStainless Steel sanitary aseptic type Zero Dead Leg Tank Discharge Bottom valve with drain valve mainly consists of a sanitary valve body, manual operating handwheel, valve stem, sealing diaphragm, drain port connector, locking assembly, and seals. It is typically connected to the bottom of the storage tank or process pipeline using quick-installation or welding methods. After installation, it fits snugly against the tank bottom without any dead angles or leaks, meeting the cleaning and sterility requirements of sanitary production. During operation, rotating the manual handwheel raises and lowers the valve stem, opening and closing the valve disc to control the flow and discharge of the medium at the bottom of the tank. The independent drain port can be opened separately for tank cleaning, completely isolating the medium from the internal driving components. Operation is simple and hygienic. A basic manual version is available, as well as customized pneumatic or electric versions to adapt to automated production lines.
