Electric Liquid Fuel Valve

Woodwards ELV electric liquid fuel valve is a small, liquid fuel-metering valve with an all-electric actuator to control the fuel flow to be supplied to a small industrial gas turbine. The ELV controls the actuator proportiona lly to a 420 mA or 20160 mA signal from a Woodward electronic control. The ELV does not need the conventional lin kage system between an actuator and a fuel-metering valve due to incorporation of an actuator and a valve. Applying an electric actuator eliminates an oil-pump -driving-gear system and hydraulic circuits, and this helps the designer cut the cost of a control system. If an electric control that accepts a 420 mA CDP signal is used, t he ELVs flow schedule will be changeable based on this signal. Users can standardize the fuel valve by using the ELV because the ELV can control various gas turbines with different flow schedules by controlling each turbines acceleration fuel schedule with an electric control.

Electrically Powered Governor Systems

The 512524 and 17121724 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. Isochronous electronic controls are available with either start-fuel limit or with switch-selected dual dynamics. Droop controls are available for certain types of parallel generator application. Load sharing devices are available for use with the isochronous models used in paralleled applications. The selected EPG actuator is mounted on the prime mover and mechanically linked to the fuel control. The rotary design and output shaft on both ends gives 30 (512524) or 35 (17121724) clockwise or counterclockwise travel to low-mass, low-friction fuel linkages. Preloaded internal return springs supply the shaft torque in the decrease-fuel direction and for shutdown should the electronic control signal be lost. A rugged cast aluminum housing permits installation of the speed control on the engine skid. In operation, the control compares the speed of the engine with the desired speed or desired load and sets the actuator position to correct discrepancies. Gain and stability adjustments tailor the governors response to the specific engine. EPG controllers with switch-selected dynamics allow stable operation at no load and brisk response when the unit is heavily loaded.

Electronic Controls Proximity Switches

Magnetic pickups (MPUs) are speed sensors that detect the speed of a prime mover, typically an engine or turbine. They are the communication link between your engine and a Woodward electronic governor control. The MPU is installed next to a drive shaft gear made of a material that reacts to a magnetic field. As each gear tooth passes the MPU, the gear interrupts the MPU's magnetic field, and an alternating voltage is developed. The frequency of this voltage is translated by the speed control into a signal that accurately depicts the speed of the prime mover. Woodwards magnetic pickups can be used with most electronic speed controls. Models are available for hazardous location installation.

Woodward Measuring Transducers

Feature True RMS sensing , Class 0.5 accuracy , RS-485 Modbus RTU Slave or Profibus DP communication

Woodwards UMT 1 Series consists of measuring transducers that feature true RMS sensing. Measured values are calculated and displayed on a two-line, 16-character LC Display. They can either be assigned to analog outputs (configurable as -20 to 20 mA, 0 to 20 mA, or 4 to 20 mA) or transmitted to a higher-level control system via RS-485 or Profibus DP interface. The primary measured values of voltage and current are used to calculate the values for active, re-active, apparent power, power factor (cosphi), kWh and kvarh. An impulse output is also provided to output kWh or kVarh values.

ProAct ITB Actuator

The ProAct Integrated Throttle Bodies (ProAct ITBs) are butterfly valves electrically actuated by ProAct actuator s to control flow output. With bore sizes ranging from 85 mm to 180 mm, these ProAct ITBs are designed for use with engines in the 1 MW to 2 MW range. This is an electromagnetic actuator with 75 degrees of travel, which alleviates the problems associated with linkages on gas engines (such as setup, non-linearity, and wear). This direct combination of throttle and ac tuator results in excellent stability and transient characteristics, and requires no hydraulics, pneumatics, or governor gear train. Therefore, you end up with an efficient, long lasting, and easily-installed throttle option.

Digital Valve Positioner

Woodwards Digital Valve Positioner (DVP) is the most advanced for use on all Woodward actuator and valve assemblies. The DVP provides a customized customer interface with advanced diagnostics to provide the most reliable system. The DVP is designed to control Limited Angle Torque and Brushless DC motor types. The DVP driver compares an input position demand signal to the valveactuator resolver feedback signal and generates an appropriate drive signal to the motor. If the DVP is connected to a valve or actuator that contains a smart ID module, the DVP will automatically read the critical valveactuator information to set the internal driver configuration for that specific unit. Once that auto-detection and configuration action has occurred the system is ready for use. Several DVP options are available. Input power is either 24VDC or 125VDC and IP30 or IP56 enclosures can be supplied. Configurable input signal protocols include EGD (Ethernet), CANopen, Analog (4-20ma or 0-5Vdc), PWM (Pulse Width Modulation). Connector, terminal block or conduit options are available to handle various wiring needs.

Electrohydraulic Power Cylinder

The EHPC is a linear integrating actuator typically used for steam turbine control-valve or valve-rack positioning. This actuator uses a low-pressure (80250 psi 5521724 kPa) hydraulic oil source and then uses three amplification stages to create the required output shaft force. As a custom (made to order) actuator, the EHPC is an actuator that is configured designed and manufactured specifically for the application. The EHPC has the flexibility to be ordered with the following configuration options: - li Single or double acting cylinder action - li Stroke & cylinder bore options - li Extend or retract current to position direction - li Top or bottom mounting attachment - li Single or dual coil input actuator torque motor - li With or without return spring - li 420 mA or 010 Vdc cylinder feedback signal - li Optional 1st & 2nd stage oil supply - li 2nd stage spring bias option - li 3rd stage spring bias option p This actuator accepts a 0200 mA (100 mA null, with an optional 15 mA null) input control signal, to position its output cylinder shaft, and outputs a 420 mA or 010 Vdc servo position indication feedback signal. An integrating actuator driver (such as a MicroNetTM actuator controller module) or an external servo position driver (such as the Woodward SPC servo position controller) is required to drive and position the EHPC. p The EHPC includes electrical position sensing on the output of the large power cylindera combination that, when used with a compatible electronic or digital control, results in powerful steam valve movement with pinpoint accuracy. The EHPC is driven by oil pressure supplied by either the turbines lubricating-oil supply or from an external independent oil supply and can be operated in any attitude. EHPC
