Woodward 8511-432 Electro-Mechanical Actuator

Product Brief Introduction High-precision electro-mechanical actuator designed for fuel valve regulation of engines and turbines. It converts electrical control signals into linear mechanical displacement to adjust fuel flow.
Tag:

Technical Specifications 4-20mA control signal input; built-in position feedback sensor. Operating temperature: -40℃ ~ +80℃.

Functional Features Linear displacement output; rapid response; closed-loop position feedback; overload protection.

Application Scenarios Diesel engines, gas engines, small industrial turbine fuel regulation.

Performance Parameters Excellent linearity, low hysteresis, stable performance under cyclic continuous operation.

Structural Characteristics Integrated sealed structure, built-in position transducer, anti-oil and dust-proof housing.

Working Principle Receives current control signal, drives internal mechanical assembly to generate linear motion, feeds back real-time position signal to the controller to realize closed-loop position control.

Installation Requirements Mount at low vibration location, correctly align connecting rod to prevent mechanical jamming during full stroke movement.

Usage Notes Conduct regular stroke inspection and lubrication; avoid impact load; periodically check the seal for oil leakage.
