is ball Industrial Valves with pneumatic actuator, pneumatic ball valve pneumatic actuators to perform relatively fast speed, the fastest switching speed 0. 05 seconds/time, so usually also called pneumatic quick to cut off the ball. Pneumatic ball valves are usually with various accessories, such as solenoid valve, air source treatment sanlian pieces, limit switch, locator, control box, etc. , in order to realize the local control and remote centralized control, in the control room can control the switch of the valve, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time and safety.

only need to use pneumatic ball valve pneumatic operation for air rotating 90 degrees of operating and small rotational torque can be closed tightly. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Generally think of ball valve is suitable for direct to do the most open and close. Ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be a whole, also can be combined.

evolved by the plug valve pneumatic ball valve. It rotates 90 degrees with the same action, different is the cock body is ball, a circular hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow. This kind of valve can be installed in any position in the pipeline.

pneumatic ball valve is to rely on the working principle of rotary valve core to keep the valve open or closed. Pneumatic ball valve switch lightweight, small size, can make a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Pneumatic ball valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve. Pneumatic ball valve in the line is mainly used for cutting speed is quick, distribution, and change the flow direction of medium. Pneumatic ball valve is a new type of valve, it has the following advantages: 1. Fluid resistance is small, its resistance coefficient with section of equal length. 2. Simple structure, small volume, light weight. 3. Compact and reliable, the ball valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system. 4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control. 5. Convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient. 6. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. 7. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. 8. Because of the power supply adopts pneumatic ball valve is a gas, general is 0. 2 - 0. 8 mpa pressure, is relatively safe. If air leakage, pneumatic ball Industrial Valves relative hydraulic, electric, gas can directly discharge, no pollution to the environment, and has higher security. 9. Relative to manual and turbine rotating ball valves, pneumatic ball valve can be large caliber configuration, ( Manual and turbine rotating ball valve is generally under 12 caliber, pneumatic ball Industrial Valves to 48 ') diameter. ） Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
