Apollo AE Series Electric Actuators
Compact and low-cost Apollo AE Series electric actuators are now available with a factory-installed 4–20-mA positioner that improves control in applications requiring flow throttling. Ideal for quarter-turn valve and damper applications, the NEMA 4 and 4X positioner offers 4–20-mA control activated incremental modulation. Other options include a locking brake, and heater and thermostat. When outfitted for modulating applications, the actuators provide push-button set-up, automatic calibration, signals for selectable input, position feedback and fail position. Other features include an adjustable dead band and locked output stall protection. All AE Series actuators are built for long service life, with hardened steel gears and standard ISO 5211 mounting interfaces, complete access to internal cams and switches, a 30% duty cycle, integral thermal overload protection, manual override, position indicator and dual conduit openings.

Pneumatic Actuators
With an extended aluminum body and a twin rack-and-pinion design, these actuators deliver constant torque output over 500,000 or more cycles. They have inboard and outboard travel stops for easy stroke adjustment to virtually any host valve’s open or closed positions. The body is hard-coat anodized to resist wear and corrosion. Bore finishing minimizes friction and wear. Nickel-plated steel pinions resist internal and external corrosion. Stainless steel assembling screws and die-cast aluminum end caps and pistons also contribute to the actuators’ long life.
