Rotary Air Valve Rotary Shaft Seals

BL-DJL complies with Meiwei FDA certification. The static ring and movable ring of the shaft seal are made of high-performance modified PTFE material, PEEK1000 and special metal processes. The shaft seal installation base, 0-ring, static ring, movable ring, and end cover can be made into partial structures, which are easy to maintain and replace. It is also used for on-site demolishing-free upgrades and replacement of equipment filler seals, skeleton oil seals and mechanical seals. The shell is a double-end heat runner.

Rotary shaft seals in rotary air valves are essential for ensuring efficient and leak-free operation in pneumatic conveying and airlock systems. These seals are installed around the rotating shaft of the valve to prevent air or material leakage between the pressurized and non-pressurized areas. By maintaining a proper seal, they help preserve system pressure, reduce energy loss, and prevent contamination of conveyed materials.

Operating under constant motion and often in dusty, abrasive, or high-temperature environments, these seals must be highly resistant to wear, heat, and chemical exposure. Materials such as PTFE, Viton, and high-grade elastomers or metal-reinforced composites are commonly used to meet these demands. Effective shaft sealing is critical to the performance, reliability, and longevity of rotary air valves, helping minimize downtime and maintenance while ensuring consistent system efficiency.
