Ball valve with pneumatic actuator is pneumatic ball valve, because the execution speed is relatively fast, 0.05 seconds / time is the fastest speed can reach, so the gas moving fast shut-off valve is pneumatic ball valve's nickname, usually equipped with various accessories in the gas valve use, such as solenoid valves, air FRL limit switch, positioners, control box, can make local control and remote centralized control is easy to implement, the switch of the valve in the control room can control directly, do not need to run to the scene or at high altitudes and the danger zone to manual control, so that the human resources and time and safety of also has the greatly improved.
The pneumatic ball valve is evolved from the plug valve. Both have the same rotation of 90 degrees, the difference is that the body of the plug valve presents a ball shape, a circular through hole or channel through its axis. The ratio of the spherical surface and the channel port should be such that when the ball is rotated 90 degrees, the inlet and outlet should be all spherical, thereby cutting off the flow. Pneumatic valve compared to manual, worm wheel and worm gear rotating ball valve is the biggest advantage is that the pneumatic ball valve can be large aperture configuration, so the gas pneumatic ball valve is widely used in petroleum, chemical, power generation, paper, atomic energy, aerospace, rockets etc. industries.
