Pneumatic sanitary ball valves feature a top-mounted structure, which reduces the number of connecting bolts required for high-pressure and large-diameter applications. This enhances valve reliability and effectively mitigates the impact of system weight on normal operation. Additionally, pneumatic sanitary ball valves offer easy cleaning and maintenance. The smooth design of their inner surfaces effectively prevents residual media, meeting the stringent hygiene requirements of industries such as food and pharmaceuticals.
● Unique Design: Its innovative upper mounting structure design significantly improves the stability and durability of the valve, especially in high pressure and large diameter applications, this design effectively reduces the number of connecting bolts, thus greatly reducing the risk of leakage caused by loose or damaged bolts.
● Easy to Slean: The smooth inner surface design of the valve is not only easy to clean, effectively prevent medium residue and pollution problems, but also reduce maintenance costs, prolong service life, especially suitable for food, pharmaceutical and other industries with high hygiene standards.

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 working principle of the pneumatic sanitary ball valve relies on the precise fit between the ball and the seat. The pneumatic actuator rotates the ball through air pressure, while the ball and seat are made of special materials to ensure a seal and smooth operation. When opened, the ball rotates 90 degrees, fully opening the passage; when closed, the ball tightly adheres to the seat, preventing leakage. The valve is also equipped with a positioning device to ensure precise operation, enhancing stability and reliability.
The unique installation structure reduces the number of connecting bolts, enhancing the reliability of the valve and ensuring stable operation under high pressure and large diameter conditions. The design takes into account ease of cleaning and maintenance; the smooth inner surface prevents media residue, meeting high hygiene standards in food, pharmaceutical, and other industries. We focus on product durability and performance optimization, ensuring that each pneumatic sanitary ball valve can stably and reliably support the customer's production process.
