Woodward 9907-358

Product Name:​ Woodward 2301A High-Voltage AC-Powered Speed & Load Sharing Controller
Product Introduction:​ A high-voltage version of the 2301A series, compatible with AC input power, eliminating the need for a DC battery supply. It is suitable for industrial power stations with AC power availability, enabling speed regulation and multi-unit load sharing.

Woodward 9906-739

Product Name:​ Woodward 9906-739 Speed Control & Load Sharing Controller
Product Introduction:​ This controller acquires pulse signals from a magnetic speed pickup to calculate actual speed, performs a differential calculation with the set speed, and outputs a corresponding drive current to control the fuel actuator for fuel quantity adjustment. In multi-unit parallel operation, it reads the load signals of other units on the bus and dynamically adjusts the output to achieve uniform load distribution.

Woodward 9902-405

Product Name:​ VSV (Variable Stator Vane) Hydraulic Control Mechanism
Product Introduction:​ The 9902-405 is a Woodward VSV variable stator vane control mechanism for non-aviation gas turbines, described alongside 9902-332 and 9902-406 in Manual 40110. It is mechanically similar to 9902-332 but differs in rotation direction, pressure ratings, and compliance specifications.

Woodward 9902-332

Product Name:​ VSV (Variable Stator Vane) Hydraulic Control Mechanism
Product Introduction:​ The 9902-332 is a classic model within Woodward's VSV variable stator vane control series, designed for non-aviation gas turbines. Its function belongs to the same product family as 9902-337, used for positioning compressor variable stator vanes, preventing compressor stall, and ensuring efficient operation under partial-load conditions. This model is described alongside 9902-405 and 9902-406 in Manual 40110.

Woodward 9902-279

Product Name:​ 505 Series Digital Controller Companion Module / Potential Converter
Product Introduction:​ The 9902-279 is a general-purpose control module/converter within Woodward's 505/505E series turbine control system family. Based on a microprocessor architecture, the 505 series is used for speed control, load distribution, synchronization, and protection of steam and gas turbines. The 9902-279 serves as a signal conversion or control interface module within the system, performing specific signal processing or power conversion tasks.

Woodward 9902-701

Product Name:​ GE LM6000 Gas Turbine Hydraulic Control Unit (HCU) — Variant of 9902-364
Product Introduction:​ The 9902-701 belongs to the same Woodward HCU family as the 9902-364 for the GE LM6000 gas turbine, with identical functional positioning. It is an order variant or improved version of 9902-364, corresponding to different engine package configurations (such as PF+, SPRINT versions) or different factory calibration parameters.

Woodward 9902-365

Product Name:​ VariStroke Linear Electro-Hydraulic Valve Actuator (Integrated Double Acting Type)
Product Introduction:​ The 9902-365 belongs to Woodward's VariStroke series of linear electro-hydraulic actuators. This series is designed for steam turbine and hydro turbine control valves (or valve groups), utilizing a low-pressure hydraulic oil source (typically turbine lubricating oil) to provide output shaft thrust. Its excellent precision and resolution make it highly suitable for steam valve control applications where turbine availability and runtime are critical.

Woodward 9902-364

Product Name:​ GE LM6000 Gas Turbine Hydraulic Control Unit (HCU)
Product Introduction:​ The 9902-364 is a Woodward hydraulic control unit designed for the GE LM6000 aeroderivative gas turbine. Used in conjunction with the Woodward NetCon 5000 Digital Control System, it controls variable-geometry actuator positions in the compressor stage. The HCU is dual-channel and contains three variable-geometry servovalves (torque motor servovalve + pilot valve), forming the core hydraulic component of the LM6000 engine package.

Woodward 9902-343

Product Name:​ 505 Series Turbine Control System Calibration and Interface Module
Product Introduction:​ The 9902-343 is a system calibration and signal conditioning module within Woodward's 505 series turbine control system, serving power management, actuator calibration, three-phase CT/PT signal interfacing, and closed-loop signal testing within the control cabinet. It is an important component of a complete turbine digital control system.

Woodward 9902-339

Product Name:​ 505 Series Digital Turbine Controller
Product Introduction:​ The 9902-339 is a 505 series microprocessor-based digital turbine controller. Its internal application software is field-programmable, guiding engineers through menu-driven software for programming configuration in power generation or mechanical drive applications.

Woodward 9902-337

Product Name:​ VSV (Variable Stator Vane) Hydraulic Control Mechanism
Product Introduction:​ The 9902-337 is part of Woodward's VSV variable stator vane control series, specifically designed for adjusting the vane angle of the compressor stage in non-aviation gas turbines (such as GE LM series aeroderivative gas turbines). It drives vane rotation via a hydraulic servo mechanism to prevent compressor stall and ensure efficient operation under partial-load and variable-speed conditions.
