Mechanical Actuators for Gas Engines

Mechanical Actuators for Gas Engines

Woodward hydro-mechanical actuators are the vital link between the electronic governor and the engine fuel-control input. This extensive product line provides a variety of control solutions for diesel, gas, and gasoline engines, or steam and industrial gas turbines.

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 has a sliding armature whose magnetic force is proportional to the input coil current. Easy to install by mounting near the fuel system and direct connecting to the fuel control rod or lever. 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.

EPG Actuation/Governing Systems

The Woodward 512/524 and 1712/1724 EPGs are three-component governing systems for 12 or 24 Vdc operation. All EPG systems include an actuator, an electronic speed control, and magnetic pickup. Both isochronous and droop controls are available. The EPG is designed for precise speed control of diesel, gas, or gasoline engines, and gas turbines. The governor is especially suited to prime movers without a mechanical drive or hydraulic oil supply for the governor, and which have low-mass, low-friction fuel linkages.

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 acutator 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 service.

Glo-Tech Hot Valve with R-Series Actuator system

Woodward’s Glo-Tech hot valve system provides precise control of high temperature gases in an on-engine environment. The Glo-Tech hot valve system is a high-temperature butterfly valve and electric actuator combination that can be used to regulate high-temperature gases in single and two-stage turbocharged reciprocating engines. The valve is designed to be positioned by an R-Series electric rotary actuator through an anti-backlash coupling capable of handling considerable misalignment.

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 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 Nxm (0.25 lb-ft) nominally over 60? travel range to operate fuel or air control devices.

ProAct™ Integrated Speed Control (ISC)

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 ProAct™ ISC can be mounted on-engine to control a diesel fuel rack or gaseous throttle via linkage or integrated throttle body. The ProAct™ ISC accepts a speed input from a MPU and can accept a position command signal from another device in the system, such as an engine control module. May be configured as a speed control or a positioner.

R-Series Electric Actuators with Integral Drivers

Woodward’s R-11 and R-30 electric actuators provide high torque rotary travel to precisely position various types of control valves and other mechanisms that operate in high-temperature, highvibration locations. In reciprocating engine applications, these valves may include: fuel throttles, wastegates, exhaust gas recirculation, compressor recirculation (bypass), waste heat recovery, and exhaust. Additional applications on reciprocating engines include variable turbine geometry turbocharger actuation.
