At Alberta Governor, our selection of actuators comes exclusively from Woodward. Woodward products are known for their high quality and durability. We are the only Woodward Authorized Independent Service Facility in our region, and are equipped to service actuators onsite or do service calls.
We currently carry the following actuators:
DYNA 2000 and DYNA 2500 linear actuators provide precise positioning with a minimal number of moving parts. Many of the moving parts normally associated with electric actuators are eliminated, prolonging the mean time between failure.
These DYNA actuators are suitable for installation on diesel, gasoline, or natural gas engines with fuel system force requirements of less than 13 pounds (58 N) of force. When paired with a Woodward controller, precise isochronous speed control of 5 to 30 HP engines (DYNA 2000) and 5 to 60 HP engines (DYNA 2500) is achieved.
The 70 degrees of rotation and compact size of the APECS DYNA 7000 actuator make mounting and interfacing with a variety of fuel systems a snap. This compact rotary actuator can be used 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.
The DYNA 7000 delivers 0.169 N-m (0.12 lb-ft) with a 70° travel range. The actuator is ideally suited for use on genset sets, pump sets, and off-road vehicles used in construction, forestry, and agriculture.
Electrically powered governor (EPG) systems are designed for precise speed control of diesel, gas, gasoline engines, and gas turbines. They are 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.
The 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.
The 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 Nm (0.25 lb-ft) nominally over 60 degree travel range to operate fuel or air control devices.
The F-Series ITB is designed to throttle air or air/fuel mixtures for gaseous engines in industrial and on-highway service. This system is designed for direct replacement of traditional throttle valves, and requires no linkage between valve and actuator. The ITB contains a return spring to fully comply with US DOT 571.124 specifications. The three sizes are designed to cover a wide range of engines, and should be selected using the sizing procedure described in this specification.
The ProAct™ P-Series FL Position Controller is a family of electric actuators 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 which accepts a position command signal from another device in the system such as a speed control.
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, high-vibration locations. In reciprocating engine applications, these valves may include: fuel throttles, waste gates, exhaust gas recirculation (EGR), compressor recirculation (bypass), waste heat recovery (WHR), and exhaust. Additional applications on reciprocating engines include variable turbine geometry (VTG) turbocharger actuation.
Woodward’s ProAct™ digital electric actuator and positioner incorporate a rotary output shaft used to accurately position steam turbine control valves. The ProAct Digital actuator includes an integral digital driver/positioner that:
Woodward’s UG and UG40 actuators offer the advantages of electronic control and load sharing systems while using the convenient, existing UG-type drives and linkages. The actuators provide the muscle for Woodward analog and digital electronic controls. The actuators can be used with diesel, gasoline, or natural gas engines, as well as with steam and industrial gas turbines. The actuators have a self-contained oil sump, so a separate oil supply is not required.
The UG actuator produces 20 J (15 ft-lb) of work over 42 degrees of rotary output.
The UG40 actuator produces 85 J (63 ft-lb) of work over 38 degrees of rotary output.
Used to control the flow of fuel or other energy source to a prime mover, EG-3P/6P/10P actuators convert an electrical signal to position a proportional rotary output shaft. These hydro-mechanical actuators provide the muscle for a Woodward 2301A, 723PLUS, or similar integrating electric control system.
EG actuators are suitable for controlling diesel and gas engines or steam and industrial or commercial gas turbines that drive alternators, DC generators, pumps, compressors, machinery, or locomotives. A Woodward hydraulic amplifier can provide larger work capacities. These actuators are also recommended for applications involving unattended starts. EG actuators can also be used for installations where prime movers operate in tandem to drive a common load. With two actuators connected in series, only one electric control is required to supply a common signal to each prime mover’s actuator.
Woodward’s TecJet™ valve is an electronic gas metering valve for single-point injection. Its integrated sensors and electronics provide the correct gas flow under all specified conditions, enabling the engine to run very lean with low emissions. TecJet’s ability to be used with a wide range of gas qualities—from methane to landfill gas to coal gas—places it among the most flexible and accurate gas metering devices on the market.
