Stainless Steel Sanitary Zero Dead Leg Flush Bottom drain Valve
 
TheStainless Steel Sanitary Zero Dead Leg Flush Bottom drain Valve is a sterile valve specifically designed for the bottom of sanitary fluid storage tanks. Driven by a pneumatic actuator, it features a dead-angle-free sealing structure and is primarily used for media discharge, switching, and sealing at the bottom of the tank. It is compatible with the bottom discharge nodes of various sanitary storage tanks. Connection methods include quick-connect, welding, and flange types.The actuation method can be selected as normally closed or normally open as needed, and valve position feedback can also be integrated. It is widely used in aseptic production scenarios such as food and pharmaceutical industries, meeting CIP/SIP online cleaning and sterilization requirements, and ensuring the sterility and cleanliness of the tank discharge process.zero dead leg flush bottom valve
TheStainless Steel Sanitary Zero Dead Leg Flush Bottom drain Valve features a quick-release clamp and aseptic sealing structure, compatible with CIP/SIP in-situ cleaning and sterilization. Pneumatic drive enables automated control, ensuring a clean flow path with no dead corners or residue, and providing excellent sealing performance.Compared to tank bottom diaphragm valves, it offers stronger erosion resistance and a longer service life; compared to tank bottom ball valves, its aseptic design eliminates dead corners more thoroughly, preventing material accumulation; compared to ordinary aseptic tank bottom valves, its pneumatic control is more efficient and stable, and its quick-release structure facilitates maintenance; compared to discharge valves, it combines discharge and aseptic sealing functions, with a compact structure and high degree of automation, making it more suitable for high-cleanliness aseptic production scenarios such as pharmaceuticals and bioengineering, offering superior overall hygiene and practicality.sanitary pneumatic aseptic tank bottom valve adopts an integrated molded valve body and mirror electrolytic polishing process, combined with food-grade composite seals, and its sealing performance and asepticity are comparable to imported products. Compared with ordinary domestic products of the same type, it has higher precision, stronger corrosion resistance, and has the advantages of high customization, short delivery cycle and fast after-sales response. The entire series has passed sanitary certification and is suitable for the stringent requirements of various aseptic storage tanks.
 
TheStainless Steel Sanitary Zero Dead Leg Flush Bottom drain Valve mainly consists of a sterile valve body, a pneumatic actuator, a valve stem, a sterile sealing diaphragm, an anti-backflow component, and an optional manual operating mechanism and valve position feedback device. It is typically connected to the bottom of the storage tank or discharge pipeline using quick-release clamps or welding. After installation, it achieves a sterile seal between the storage tank and pipeline,ensuring no material residue and no leakage, meeting the cleaning and sterilization requirements of sanitary production. During operation,compressed air is input to the pneumatic actuator, driving the actuator to move the valve stem up and down. The valve stem then presses or releases the sealing diaphragm in the valve body flow channel, achieving the opening and closing of the medium for discharge and sealing. The diaphragm completely isolates the medium from the driving components, while the anti-backflow component, in conjunction with the sealing structure, effectively prevents backflow of the medium in the pipeline, ensuring sterile conditions throughout the process. This valve can be equipped with pneumatic, manual, and electric actuation modes as needed.The pneumatic version is suitable for automated production lines,the manual version can be used for emergency operation, and the electric version supports remote precise control, meeting the operational needs of different production scenarios.
