Spring Return and Double Acting Pneumatic Quarter-Turn Actuators for Output Torques to 27,624 lb.in.

Features & Benefits:

  • Compact rack and pinion design utilizes the whole piston area to develop output torque.
  • Pistons with integral rack drive reduce the number of dynamic seals, minimizing air leakage.
  • Double pistons nullify sideloads on the pinion shaft, minimizing bearing wear and extending life.
  • Internal air porting eliminates external tubing.
  • Hard anodized aluminum body with external electrostatic powder coating (ESPC) finish protects against corrosive environments.
  • Female output drive enables direct mounting of most Keystone valves, eliminating special adaptation connections and assuring correct alignment.
  • Bottom entry pinion shaft simplifies assembly and provides anti-blowout feature.
  • Anti-friction piston pads ensure no metal-to-metal contact, providing smooth operation. Ideal for modulating or on/off control applications.
  • Adjustable travel stops standard in both directions on sizes 065 to 181.
  • An extensive range of standard accessories are available for direct mounting.
    • Solenoid valves
    • Limit switchboxes
    • Positioners
    • Declutchable manual override gearbox
    • High visibility indicator
