The Q641F stainless steel pneumatic ball valve is composed of a high-precision pneumatic actuator and a precision-cast ball valve. It is mainly divided into two categories: pneumatic soft-seal ball valves (≤200°) and pneumatic hard-seal ball valves (≤550°). Pneumatic ball valves have advantages such as compact structure, small size, reliable operation, low flow resistance coefficient, good sealing performance, easy maintenance, convenient installation, and strong adaptability.

The pneumatic ball valve can be equipped with travel limit switches, solenoid valves, pressure reducers, and a 0.4-0.7MPa air source to achieve switch operations, and send two pairs of passive contact signals to indicate the opening and closing of the valve.

Stainless steel pneumatic ball valves are particularly suitable for occasions where the medium is viscous, contains particles, or has fibrous properties. They are widely used in industrial automatic control systems such as petroleum, chemical engineering, teaching equipment, light industry, high-pressure equipment, pharmaceuticals, and paper-making for remote centralized control or local control.
