Pneumatic ball valve specific classification are: stainless steel pneumatic ball valves, pneumatic ball valve, plastic sanitary pneumatic ball valves, carbon steel pneumatic ball valve, ball valve, two ventilation tee pneumatic ball valves, pneumatic ball valve spool, then what is the working principle of the pneumatic ball valve? Every instrument valves for everybody introduction: under the working principle of the pneumatic ball valve, pneumatic ball valve only need to use pneumatic operation USES 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. Is the ball valve with pneumatic actuator, pneumatic ball valve pneumatic actuator execution speed is relatively fast, the fastest switching speed 0. 05 seconds/time, so usually also called pneumatic quick to cut off the ball. Pneumatic ball valve is made up of cock. 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 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.
