Pneumatic flange ball valve is connected by a flange; is composed of forged steel, carbon steel, stainless steel and other materials of various ball valve products and pneumatic actuators. It is petroleum, chemical, light industry, paper and other industrial automatic control systems in the media cut off, distribution and regulation. Pneumatic flange ball valve has high safety factor, simple structure, low fluid resistance and convenient operation. The pipeline sealing performance of flange connection is better, and the maintenance and replacement are more convenient. It can be operated on site or controlled remotely, which saves human resources and time to a great extent.
