Specifications

Actuator

Output Shaft: 0.500-36 inch serration on output shaft. Opposite side used for feedback device. (Other configurations

available upon request.)

Operating Temperature Range: –40 to +100 °C (–40 to +212 °F) operating environment. Contact Woodward for

extreme temperature installation procedures.

Feedback: Brushless Hall Effect feedback device directly connected to actuator shaft.

Installation: May be mounted on 2.250 inch (57.15 mm) diameter male pilot concentric to the terminal shaft using

four bolts through the actuator or with four 0.312-18 inch bolts into the base (M8-6H metric optional). The actuator

may be mounted in any attitude.

May be connected directly to butterfly shaft, or may be linked to rack or valve.

Weight: The ProAct I and ProAct II actuators each weigh 6.9 kg (15.25 lbs).

Construction: All external surfaces are resistant to water and salt water corrosion. Actuator is waterproof at normal

water hose pressure and meets IP54 rating. Do not high-pressure wash.

Vibration and Shock Tested: Tested to US MIL-STD-810C.

MIN Fuel Return Spring: The actuator is equipped with a light spring return toward min fuel to prevent drift in case

of position signal interruption. Normal operating conditions do not require spring return, as the actuator is powered in

both the increase and decrease directions.

Direction of Rotation: All models are capable of either clockwise or counterclockwise rotation to increase fuel.
