Compared with manual, worm gear of the ball valve pneumatic ball valve

refers to the pneumatic ball valve ball valve with pneumatic actuator. As a result of the pneumatic actuator execution speed is relatively fast, switching speed can reach. Seconds/time, so pneumatic ball valve can also be called pneumatic quick to cut off the ball. Pneumatic ball valves in use typically with various accessories, such as solenoid valve, air source treatment sanlian pieces, limit switch, locator, control box, etc. , to achieve local control and remote centralized control in the control room can directly control the switch of the valve, do not need to run to the field manual control or high altitude and dangerous, this largely saves human resources and time and safety. Pneumatic ball valve is made up of cock. Both have the same rotation movement, the different is the cock body in sphere shape, has a circular hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotation, should all present in the inlet and outlet sphere, thus blocking flow. And pneumatic ball valve compared with manual and worm gear rotating ball valve advantages of pneumatic ball valve can be large caliber configuration, so the pneumatic ball valve is widely used in petroleum, chemical, power, papermaking, atomic energy, aerospace, rocket, etc.
