Woodward 8245-012 Hydraulic Linear Actuator

Product Description

Model: Woodward 8245-012 The 8245-012 is an F-Series electro-hydraulic linear actuator from Woodward. It uses a torque motor to regulate hydraulic flow and drive a double-acting servo piston for precise linear movement, to control fuel rack or throttle position for diesel and gas engines. This actuator requires an external hydraulic supply and is commonly paired with Woodward electronic speed governors. Rugged sealed housing offers good vibration resistance and oil tolerance. It features fail-safe (minimum fuel) protection upon loss of control signal, widely supplied as spare part for prime mover speed control systems.
