Pneumatic sanitary ball valves adopt an upper mounting structure, reducing the number of connecting bolts required under high pressure and large diameter conditions, thereby enhancing valve reliability and overcoming the impact of system weight on normal valve operation. Pneumatic sanitary ball valves also feature easy cleaning and maintenance; their smooth inner surface design effectively prevents residual media, meeting the high hygiene standards required in food, pharmaceutical, and other industries.
● Unique Design: Its unique upper installation structure design greatly improves the stability and durability of the valve, especially in high pressure, large diameter applications. This design greatly reduces the number of connecting bolts, thus reducing the risk of leakage caused by bolt loosening or damage.
● Easy to Slean: The smooth design of the inner surface of the valve not only facilitates cleaning, effectively avoids the problem of medium residue and pollution, but also reduces maintenance costs and extends service life. It is especially in line with the industry standards of high hygiene such as food and medicine.

Q1:What is the main suitable of this valve?
This product is especially suitable for steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.
Q2:What mechanical principle is used?
The mechanical principle of pneumatic sanitary ball valves is primarily based on the precise design of the ball and seat. When the pneumatic actuator receives a control signal, it drives the ball to rotate through air pressure. The ball and seat are made from special materials to ensure sealing performance while achieving smooth switching actions. In the open position, the ball rotates 90 degrees, completely clearing the passage for free flow of the medium; in the closed position, the ball tightly adheres to the seat, effectively preventing media leakage. Additionally, pneumatic sanitary ball valves are equipped with limit and positioning devices to ensure the precise position of the ball during opening and closing, further enhancing the stability and reliability of the valve.
The unique upper mounting structure not only reduces the number of connecting bolts but also significantly enhances the overall reliability of the valve, ensuring stable operation under high pressure and large diameter conditions. The valve design fully considers ease of cleaning and maintenance; the smooth inner surface effectively prevents media residue, thus meeting the stringent hygiene standards of the food and pharmaceutical industries. We also focus on product durability and performance optimization, ensuring that each pneumatic sanitary ball valve provides stable and reliable support for customers' production processes.
