The CPC (Current to Pressure Converter)
The Woodward CPC Current to Pressure Converter is designed for positioning steam and fuel valves and/or the associated servos. A 4–20 mA in/out signal is linearly and proportionally converted into a hydraulic output pressure. The CPC can thus interface with any electronic control, such as Woodward MicroNetTM systems and the Woodward 505 Control. It connects to pressure-operated servo systems and single-acting power cylinders. The CPC is suited for new as well as retrofit applications.

Hydraulic Amplifier
The electrically controlled Hydraulic Amplifier is a pilot operated, linear servo actuator used in conjunction with the Woodward 2301, 505 Series or MicroNetTM electronic controls. The amplifier contains a Woodward EG-3P actuator which converts the electric control signal to a rotary output which controls the servo output position taken by the amplifier. The amplifier is capable of operating the control mechanisms for steam turbines or large engines which require relatively large forces and work capacity.
Hydraulic Amplifier Product specificationThe TG-13E and TG-17E proportional actuators
The TG-13E and TG-17E proportional actuators are self-contained electrohydraulic actuators for use on steam turbines where isochronous control, load sharing, or other functions are required. They can be used with all available Woodward electronic governor controls and accessories. The TG actuators convert an electrical signal to a corresponding proportional output shaft position to position the valve which controls the flow of steam or energy medium to the turbine. They are intended for controlling small steam turbines driving such loads as alternators, dc generators pumps, compressors, fans or paper-making machines.
TG-13E and TG-17E actuator Product specificationThe ProAct™ Digital Plus actuator
The ProAct™ Digital Plus actuator is intended to be mounted on-engine to control varying functions including (but not limited to): fuel rack positioning, timing control, throttle valve, and wastegate positioning. The actuator is effectively a positioner with an integral driver, which will accept a position command signal from another device in the system such as a speed control. The ProAct Digital Plus actuator includes an integral digital driver capable of controlling the actuator, communicating with the outside control system, and containing on-board software and intelligence to realize monitoring and customizing functions.
ProAct Product specificationThe TM-25LP and TM-200LP actuators
The TM-25LP and TM-200LP actuators are electrohydraulic, proportional actuators for positioning steam and fuel-control valves requiring low/high force linear inputs.

The APECS® 2000 and APECS® 2500 linear actuators
The APECS® 2000 and APECS® 2500 linear actuators provide accurate precise positioning with a minimal number of moving parts. Many of the moving parts normally associated with electric actuators are eliminated, prolonging the MTBF (mean time between failure). These actuators are easy to install by mounting near the fuel system and direct connecting to the fuel control rod or lever. In most installations, the normal rotary-torotary connection is eliminated, resulting in a more trouble-free and accurate control system. The actuator is suitable for installation on diesel, gasoline, or natural gas engines with fuel system force requirements of less than 13 pounds (58 N) of force.
