Rack and Pinion Pneumatic Actuator

Rack and Pinion Pneumatic Actuator

Rack and Pinion Pneumatic Actuator

Item Number: HPA

The cylinder body of the pneumatic actuator is made of extruded aluminum alloy and is treated with hard anodizing. The inner surface is hard in texture, high in strength and hardness. Sliding bearings made of low-friction materials avoid direct contact between metals, with low friction coefficient, flexible rotation and long service life.

  • Seat Material: 2.5 bar to 8 bar
  • Design Standard: -20~+80Degree
  • Body Material: Hard anodized extruded Aluminium alloy
  • Nominal Size: Standard adjustable 90°±%

Description

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.
