Rack and Pinion Pneumatic Actuator

الوصف

Rack and pinion pneumatic actuator is a type of actuator that uses compressed air to move a piston that is connected to a rack and pinion mechanism.  The rack is a straight, toothed bar, while the pinion is a small, toothed wheel that engages with the rack.  When the pneumatic actuator receives a signal, the compressed air enters the piston chamber and pushes the piston, which moves the rack and pinion.  As the rack moves, it rotates the pinion, which, in turn, moves the output shaft or valve stem.  The output shaft or valve stem is typically mounted on the top of the actuator and moves in a rotational motion to adjust the position of a valve or other control element.  This type of actuator is commonly used in process control applications, such as in the oil and gas industry, chemical plants, and power generation plants.
