Woodward PG12R/PG12L Actuator

The PG Actuator converts a given electrical input signal from the turbine control and converts it to a proportional hydraulic output.

The PG Actuator is used to replace PGA/PGE-type governors, providing the advantages of electronic control with the convenience of the existing PG-type drive and linkage. An LVDT is available to provide voltage feedback proportional to fuel-rack position. We recommend the PG Actuator for installation involving unattended starts.

Woodward MicroNet Plus

The MicroNet Plus control is a VME-based, modular control system with redundant or simplex CPU and power supply options and a variety of I/O module choices. I/O Module selection is customized to match customer requirements. I/O can be configured in any combination of simplex, duplex, or triplex and in any combination of analog, discrete, and specialty modules. I/O modules allow for hot replacement without removing control power.

The MicroNet Plus control utilizes Woodward’s proven graphical application programmer (GAP) software. This function block format programming language provides an efficient means to program prime mover control logic.

Woodward GS6 Gas Valve with On-Board Driver

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.
