pneumatic rack & pinion

Designed and manufactured for the ultimate durability and reliability, “Apollo”® pneumatic rack &
pinion actuators provide outstanding service life.

“Apollo”® rack & pinion actuators have replaceable insert drive adapters in all but the largest models,
and many units have dual ISO 5211 “F” series bolt patterns. The numerous actuator drive and bolt
pattern combinations allow direct mounting of several valve styles


  • body: Cast aluminum, yellow chromate powder coat finish
  • End caps: Die cast aluminum, yellow chromate powder coat finish
  • Pistons: hard anodized die cast aluminum
  • Pinion: Aluminum alloy, hard coat anodized finish
  • Drive inserts: Extruded aluminum, hard-coat anodized finish
  • Preloaded concentric springs: Spring steel, electrophoretic finish
  • Bushing: Polyoxymethylene(POM)
  • O-ring seals:
    • standard temp
    • high temp
    • low temp
  • Fastener: Stainless or alloy steel, Delta*-Tone coated



Designed to be rugged and easily installed, “Apollo”® AE Series electric actuators deliver the most
desirable features and performance in their class. All sizes now CSA listed as standard*.
