• 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.
• An extensive range of standard accessories are available for direct mounting: Solenoid valves、Limit switchboxes、Positioners、Declutchable manual override gearbox、High visibility indicator.
