The main function of the pneumatic butterfly valve positioning component is to eliminate all kinds of hysteresis and incongruity. It is mainly used in the composite position adjustment system to achieve reverse operation, manipulate non-standard execution components, and the positioning component receives the signal sent by the pneumatic adjustment component, and then generates a gas pressure signal of corresponding proportion according to the signal, In order to achieve the effect of controlling the pneumatic regulating parts, according to the work rules, it can be divided into position moving balancing parts and torque balancing parts.

Operation and application of pneumatic ball valve
1) Before operation, it must be acknowledged that pipelines and valves have been washed. 　　
2) The operation of the valve drives the valve rod to rotate and complete according to the size of the input signal of the actuator: when the valve rotates 1/4 circle (90 °) in the positive direction, the valve is closed. When the valve is rotated 1/4 turn (90 °) in the opposite direction, the valve is open. 　　
3) When the direction indicating arrow of the actuator is parallel to the pipeline, the valve is open; When the arrow is straight with the pipeline, the valve is closed.
