Woodward Industrial Turbine Fuel Control Valves
Fuel Control Valve Drivers for Gas Turbines
Digital Valve Positioner (DVP)
Woodward’s 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 valve/actuator 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 valve/actuator 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.
