Woodward Gas Engine Actuators

F Series Modular Actuator
The Woodward F Series Modular Actuator is an electric bi-directional actuator with an integral driver. The actuator accepts a position demand signal from a master controller and drives the 0-70 degree output shaft to the demanded position based on an internal shaft position sensor. The actuator can accept a PWM, J1939 CAN, 4-20 mA, or 0-5 V position demand signal. The electric actuator requires no hydraulics, pneumatics, or gear train. The Woodward F Series Modular Actuator is designed to be engine-mounted for various position control functions on reciprocating engines used in industrial and on-highway service. Position control application examples can include fuel rack positioning, throttle valve positioning, waste-gate valve positioning, as well as other engine position control functions.

L Series Speed Controller
The Woodward LCS Integrated Engine Control System is the first engine speed control to deliver so much in a package this compact, and it can also deliver a big savings in production and field support. Since the Woodward LCS Control System is microprocessor-based, it can easily be programmed to match the operating parameters of every engine you produce. All it takes is a PC and a simple, plug-in download on your production line. With many built-in functions, this microprocessor-based speed control allows a high-volume OEM or packager to stock one part number, but implement a wide variety of engine control strategies by configuring the four auxiliary inputs at their factory.

L Series Position Controller
The Woodward L Series Position Controller provides a building block approach to total engine management. The microprocessor-based bi-directional actuator design easily attaches to fuel pumps, mixers, or throttle bodies. The Woodward L Series Position Controller accepts a position command and drives the 0-60 degree output shaft to the commanded position based on an internal shaft position sensor. The high-efficiency torque motor delivers 0.34 N·m (0.25 lb-ft) nominally over 60 degree travel range to operate fuel or air control devices.

ProAct Digital Plus Actuators
The Woodward 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 Woodward 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 ISC Integrated Speed Control
The Woodward ProAct Integrated Speed Control (ISC) is an electric actuator with an integrated electronic driver capable of diesel or gaseous engine speed control or positioning tasks. The Woodward ProAct ISC can be mounted on-engine to control a diesel fuel rack or gaseous throttle via linkage or integrated throttle body. The Woodward ProAct ISC accepts a speed input from an MPU and can accept a position command signal from another device in the system such as an engine control module.Configured as a speed control, the Woodward ProAct ISC offers speed control with software-selectable speed set points, dynamics, fuel limiting, and start/stop behavior.Configured as a positioner, the Woodward ProAct ISC offers position control with software selectable CW/CCW operation and field calibration.

ProAct I & II Electromagnetic Actuators
Producing 2.5 and 5 ft-lb transient work respectively, the Woodward ProAct I & II actuator systems are electric powered governor systems designed to provide precise electronic control and limiting for gas and diesel engines. They provide multi break-point control which allows for removal of non-linear linkages.

ProAct III & IV Electromagnetic Actuators
Producing 10 and 20 ft-lb transient work respectively, the Woodward ProAct III and IV actuator systems are for actuation of larger diesel, gas, and gasoline engines. These systems are well suited for engines without a mechanical drive or hydraulic-oil supply.

UG Actuator
The Woodward UG Actuator offers the advantages of electronic control and load sharing systems while using the convenient, existing UG8 type drives and linkages. The actuator provides the muscle for Woodward analog controls such as the 2301A, as well as Woodward digital controls such as the 500 series, 700 series, and the IGEM engine management system. The Woodward UG Actuator can be used with diesel, gasoline, or natural gas engines, as well as with steam and industrial gas turbines. The Woodward UG Actuator has a self-contained oil sump so a separate oil supply is not required.

PG PL Actuator
The Woodward PGPL Actuator/Driver is an electro-hydraulic actuator with a proportional driver interface which can be used with electronic controls providing a 0 to 200 mA position signal. The actuator is designed for use with Woodward 2301A series, 700 series, Peak 150, and 505 digital controls.

TM 55P Proportional Actuator
The Woodward TM 55P Actuator is an electrohydraulic, proportional actuator for controlling diesel and gas engines or steam and industrial gas turbines. It is designed for use with Woodward analog and digital controls. The Woodward TM 55P will interface (with an adapter) directly to Woodward liquid and gas fuel valves. It is particularly well suited for use in control systems requiring a rotary mechanical output that is proportional to electrical input.

M 55 Integrating Actuator
The Woodward TM 55 is an integrating type actuator used for controlling diesel and gas engines or steam and industrial applications of gas turbines, and is designed for use with an adapter directly to Woodward liquid and gas fuel valves. The Woodward TM 55 has an electrical position sensor which provides a feedback signal to Woodward electronic controls. This combination allows closed loop control of the actuator output-shaft position.

Dyna Actuators

Dyna 2000 & 2500 Linear Actuators
The Woodward Dyna 2000 and Dyna 2500 linear actuators provide accurate precise positioning with a minimal number of moving parts. This simple design of a proportional electric solenoid has a sliding armature whose magnetic force is proportional to the input coil current. 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-to-rotary 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.

Dyna 7000 Rotary Actuator
The Woodward Dyna 7000 Rotary Actuator provides a new dimension in size and versatility for spark-ignited and diesel engines. This proven rotary design has been field tested over the last ten years. This simple design of a proportional electric solenoid has a rotating armature whose angular position is proportional to input coil current. The 70 degrees of rotation and small size enhance the overall mounting and interface with a variety of fuel systems. The actuator is suitable for installation on gasoline, natural gas, and diesel engines. On carbureted and throttle body applications, a direct connection between actuator shaft and butterfly shaft is possible, thus eliminating external linkage.
