The fluid resistance of pneumatic ball valve is small, the fluid resistance of pneumatic ball valve is the smallest of all the valves, its start and stop are rapid and easy, it takes compressed air as power, through piston rack, gear machinery drives valve rod, which makes the ball rotate 0~90°with the torque output by angle stroke, it can quickly complete start, stop or adjustment.

Ball core channel is smooth, it is difficult to deposit media, which can be implemented pipeline for ball through. Structure is simple, light weight, sealing performance is good.
