What is the working principle of pneumatic ball valve

Pneumatic ball valve ball is transformed from the plug valve, its center of the ball for the rotation of 90° action, the ball around the valve body center line for rotation to achieve the opening, there is a circular through hole or channel through its axis. When the ball center rotates to 90°, the valve is in the closed state. When the actuator is working, it only needs a small torque to close the valve tightly, so as to achieve the principle of quick cut-off.

Pneumatic ball valves are mainly used in the rapid cut off, distribution and change of media in the flow of the pipeline. The use of v-shaped sphere can accurately adjust the media flow. Pneumatic ball valve it opens and closes quickly, suitable for the use of large and small caliber.

Pneumatic ball valve structure has two kinds of distinction, one is a v-shaped ball core, it adopts a fixed structure, the ball core with a v-shaped incision, the actuator is installed on the locator to achieve the proportion adjustment of the medium containing fiber, granular. The other is the o-type ball core, the o-type ball valve valve core is floating precision casting, the flow channel mouth and the pipe diameter is the same, mainly used as a cut-off switch.
