Meet the TecJet valve. The TecJet is an electronic gas metering valve for single-point injection. It has integrated sensors and electronics, which provide the correct gas flow under all specified conditions.

In general, a separate engine control system, like the E6 Lean-Burn control, calculates the desired gas flow from the different engine and gas parameters. This desired gas flow is transmitted through a CAN link to the TecJet valve(s). The TecJet valve ensures that the desired gas flow is attained, automatically compensating for changes in gas pressure and gas temperature.

The Woodward DVP is the state-of-the-art driver for electric actuation. It features a rugged and compact design. The DVP is designed for use with various Woodward valves and actuators. It provides positioning

based on a demand signal from the control system. Multiple input type configurations allow the DVP to be used with many different turbine controllers. The driver supports redundant installations.

The DVP is designed to control valves and actuators with either limited angle torque (LAT) or brushless DC (BLDC) motor types. The driver positions based on resolver feedback located on the valve or actuator. The DVP uses the latest in Woodward control architecture, the robust controller to provide high-speed precise valve control.

The liquid shutoff valve is a three-way valve designed to rapidly shut off all liquid fuel flow and prevent leakage to the turbine. In the de-energized state, the valve diverts inlet flow to bypass ports, preventing pressure damage to positive displacement fluid systems.

Normal installation of the 45 lb (20 kg) valve is in the fuel line between the fuel regulating valve and the turbine.

The valve is designed for a normal operating supply pressure of up to 1200 psig (8274 kPa) and has a rated flow of 30 000 lb/h (13 608 kg/h) based on US MIL-C-7024 calibrating fluid at 70 °F (21 °C).

Woodward’s LQ25T liquid fuel metering valve is designed for use on industrial and aeroderivative gas turbine engines in the 6000 kW to 42 000 kW output power range. The valve is a two-way flow control valve utilizing a throttling type of delta P regulator. This allows the valve to control pressure drop across the metering port without bypassing fuel, making it ideal for centrifugal or other pressure source type fuel pumping systems. The assembly provides a reliable, cost-effective interface between electronic engine control systems and gas turbines used in power generation, mechanical drive and marine applications. The LQ25T valve utilizes corrosion-resistant, shear-type metering components that are positioned by a high-torque actuator to assure extended operation in all types of liquid fuel service.

The LQ25T valve is compatible with diesel fuels, JP series, naphthas, kerosenes, gasolines, and other distillates conforming to nationally or internationally recognized standards for utility, marine and aviation gas turbine service.

The LQ6 provides the flow range, accuracy, and response characteristics necessary for the control of industrial gas turbines in the 3 MW to 15 MW power range. By integrating Woodward’s proprietary electric actuation technology with a proven fuel-metering concept, exceptional performance and robustness are achieved in a compact, cost effective package. The use of onboard driver electronics simplifies system design and reduces installation space, time, and cost.

Please refer to Woodward Installation and Operation Manual 26515 for complete details of this product, its application and installation.

The GSOV25 HT fuel isolation valve provides shutdown on a gas turbine by rapidly halting the flow of gaseous fuel. The supply pressure is used to move a spring- loaded piston in the valve. When the valve is energized, gas pressure drives the spring-loaded piston open, admitting fuel to the turbine. When the current signal to the electrical solenoid is interrupted, the spring loaded second-stage piston changes states to vent off primary control pressure. The main spring then forces the primary piston to the seal, stopping all flow.

The Servo Position Controller (SPC) is a servo-valve driver that accepts a DeviceNet™ * or (4 to 20) mA based position demand signal from a system controller, and accurately positions proportional or integrating servo-valves. The SPC has the required accuracy, responsiveness, and redundancy required for steam or gas turbine fuel valve control. For valve position sensing, the SPC accepts feedback signals from one or two (redundant) ac devices or one dc device.

The Woodward GS6 gas fuel metering valves are designed to meet the high performance standards required for the control of fuel to industrial gas turbines. The assembly provides reliable, cost- effective interfaces between the electronic engine control system and the gas turbine as applied in power generation, compressor, or mechanical drive applications. The valve can be used in a single valve configuration for single- manifold base turbines or in multiple valve configurations for Dry Low Emission turbines.

The Woodward GS16 gas valve is suitable for use on industrial gas turbine engines with maximum power ratings between 10 and 50 MW. The assembly provides a reliable, cost-effective interface between electronic control systems and gas turbines used in electrical power generation, compressor, or mechanical drive applications. The valve assembly can be used for base turbines or in multiple valve configurations in Dry Low Emission turbines.

The 3103-gas valve is integrally mounted with an adapter to a TM-55P Actuator receiving electric positioning signal from an electronic control. The valve/actuator is designed for use with all Woodward electronic controls to control industrial applications of gas turbines.

The TM-55P is an electrohydraulic, proportional actuator which converts electric control input to angular shaft output for positioning the rotary fuel metering sleeve of the valve. The essential element of the actuator is a torque motor servo valve which generates a differential pressure applied to both ends of, and to operate, the second stage spool valve. Input current to the torque motor gives proportional displacement of the spool valve and subsequent proportional movement of the servo piston.
