Model AK Pneumatic Actuators
Compact and light-weight actuator, equipped with a guide rod for smooth operation and extended durability


  • Double acting and single acting type are of the same shape and dimension

  • Guide rod eliminates side loading of the piston for smooth actuation and greater durability
  • Double rack design allows for a larger cylinder bore and shorter piston stroke, resulting in a more compact unit and high torque
  • ISO 5211 mounting pattern to provide the greatest flexibility for valve adaptation
  • Air supply port (piping seat) and stem top conform to NAMUR standards for simple and direct mounting of accessories
  • Interchangeable spring return sets according to each operating pressure/torqe.
