The pneumatic sanitary butterfly valve is a valve device designed specifically for sanitary-sensitive industries such as food, pharmaceuticals, and bioengineering. Combining a pneumatic actuator with a sanitary butterfly valve body, it features rapid opening and closing and no contamination residue.
The pneumatic sanitary butterfly valve is made of stainless steel and food-grade sealing materials, with an electropolished surface to ensure no media residue and avoid contamination risks. Its structural design emphasizes lightweight construction, rapid opening and closing, and ease of assembly and disassembly, making it adaptable to various installation positions. The performance parameters of the compatible actuators cover cylinder type, control method, and interface specifications.

Pneumatic sanitary butterfly valve Performance Advantages
Pneumatic Actuator
Double-acting: Compressed air alternately enters two chambers, driving the valve stem in both forward and reverse directions for rapid opening and closing (response time ≤ 0.5 seconds), suitable for high-frequency switching scenarios.
Single-acting (Spring Return): When the air supply is interrupted, the spring automatically returns the valve to the closed state, ensuring safe isolation, commonly used for backflow prevention or emergency shut-off.
Double-acting/Single-acting Modes:
High Torque Output: Employs a rack and pinion or shift fork transmission structure, increasing output torque by 40%, capable of driving large-diameter valves above DN150.
Air Supply Adaptability: Operating air pressure range 0.4-0.7MPa, compatible with most factory compressed air systems.
Control Accuracy and Reliability
Flow Regulation: Achieves linear flow control through the rotation of the disc (0°-90°), with a high flow coefficient and low flow resistance.
Sealing Performance: Employs a soft-seal structure, with a leakage rate lower than the national standard (GB/T 13927-1992), ensuring no leakage pollution.
Durability: The pneumatic actuator features a mirror-finish cylinder and an oil-free lubrication design, resulting in a low coefficient of friction and a lifespan exceeding 1 million opening and closing cycles.
Pneumatic sanitary butterfly valve Applications:
Food and Beverage Industry
Dairy Production Lines: Controlling the transport and blending of fluids such as milk and yogurt to prevent cross-contamination.
Beer Brewing: Regulating the flow rates of steam, wort, and beer during saccharification, fermentation, and bottling to ensure consistent flavor.
Beverage Mixing: Precisely controlling the ratio of syrup, water, and carbon dioxide to ensure stable product taste.
Pharmaceuticals and Bioengineering
Aseptic Preparation Production: Achieving automatic switching between high-temperature, high-pressure fluids in CIP (Clean-in-Place) and SIP (Steam In-Place) systems.
Cell Culture: Precisely controlling the delivery of culture media and buffer solutions to maintain a stable reactor environment.
Vaccine Production: Ensuring no contamination transfer of fluids during critical steps such as virus inactivation and purification.
Cosmetics and Fine Chemicals
Emulsification Processes: Adjusting the mixing ratio of oil and water phases to improve product uniformity.
Bottling Lines: Controlling the addition of trace ingredients such as flavorings and colorings to ensure batch consistency.
Clean Steam and the Beverage Industry
Steam Piping: Controlling the distribution of clean steam in food processing plants to prevent condensate contamination.
Beverage Filtration: Adjusting the backwashing flow rate of the filter media in wine and spirits production to extend the filter media's lifespan.
