The pneumatic ball valve is a pneumatic actuator with a ball valve. Pneumatic actuators perform relatively fast, and the fastest switching speed is 0.05 seconds / times, so it is usually called pneumatic quick shut-off of ball valves. The pneumatic ball valve is usually equipped with various accessories such as the solenoid valve, the gas source treatment triad, the limit switch, the locator, the control box, etc. to achieve local control and long distance centralized control. In the control room, the valve switch can be controlled. It does not need to run to the scene or at the high altitude and the dangerous zone. It saves human resources, time and safety.
