Ball valve body can be a group, also can be combined. Ball valve itself is the main distinctive local compact structure, easy operation and maintenance, suitable for use in water, solvents, acids and natural gas and other medium of general office, and also suitable for use in conditions of despicable medium, such as oxygen gas, oxygen, hydrogen, methane and ethylene, etc. This kind of valve is installed in the pipeline can be arbitrary position. Office principle of pneumatic ball valve in pneumatic operation USES air Marine valve rotating 90 degrees of operating and small rotational torque can close the tightness. 。 Absolute equality of the valve body cavity to supply medium with the flow resistance is small, straight. The proportion of the surface of the ball and intersection should be so, that is when the ball rotate 90 degrees, on the surface of the inlet and outlet should be all flash ball, so cut off the flow. Q: principle of pneumatic ball valve development progress and office answer: progress in development: pneumatic ball valve is by developing and plug valves. Generally think that the most open and close fitting for direct do use ball valve, ball valve but recent developments have preset into with throttling and stem flow. It rotates 90 degrees with the same action, different is the cock body is spherical stereo, a round hole or channel through its axis.
