Pneumatic ball valves are used as a diverter or selector valve depending on specific application needs. This ball valve controls valve opening and closing by compressing the air, with the speeder used to adjust the time. Compared to other valves, pneumatic valves offer a faster opening and closing, and are compatible with an extensive array of media, including water, air, oil, acid and alkali corrosive mediums and low viscosity fluids in chemical industries.
