Gear Operation Ball Valve

Replacement of packing 45 for ball valves with gearboxes - ball valves with gearboxes (1) Close shutoff valves upstream and downstream of ball valves. Release the pressure in the pipe before and after the ball valve. (2) Make the ball valve fully closed.

Manual valves generally use deceleration augmentation devices, the main role is to make large caliber valves can be pulled. The opening moment of the valve with large caliber is relatively large, and the power of ordinary people can not be pulled directly. Through the deceleration booster, people can pull the valve to open or close the valve.

Butterfly valves, ball valves commonly used worm gear box boost.

The spur gear mechanism is commonly used in gate valves and globe valves.

A ball valve is a valve driven by a stem and rotated around the axis of the ball valve. It can also be used for fluid regulation and control. Hard-sealed V-type ball valve has strong shear force between V-type ball core and metal seat of hardfacing carbide, especially for medium containing fibers and micro-solid particles. In the pipeline, the multi-pass ball valve can not only flexibly control the confluence, diversion and flow switching of the medium, but also close any channel and connect the other two channels. Valves of this type shall generally be installed horizontally in pipes. Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves according to the driving mode.
