Woodward

Woodward is a manufacturer of energy control solutions whose industrial products are used to govern, control, and protect turbines, compressors, and engines in power generation, oil and gas, and industrial applications worldwide. Woodward's industrial hardware covers turbine governors, speed controls, overspeed protection devices, electro-hydraulic actuators, electronic control platforms, and gas turbine valve systems; technology installed wherever precise control of rotating machinery is operationally critical. PLC Direct supplies Woodward industrial hardware for customers sourcing replacement components and installed-base parts to maintain existing Woodward-equipped turbine and engine control systems.

Why Choose Woodward Industrial Control Products

Woodward is recognized for turbine and engine control technology that addresses the most demanding requirements of continuous industrial machinery operation. Woodward hardware is built for applications that require precise speed control, load control, overspeed protection, and actuator response to keep rotating equipment running safely and efficiently under varying load conditions.

Woodward industrial control systems are commonly installed in:

• Gas turbine and steam turbine power generation plants requiring speed governing and load sharing control

• Oil and gas processing facilities with gas and steam turbine compressor drive applications

• Offshore platforms and LNG facilities with turbine-driven compression and pumping equipment

• Hydro power plants requiring turbine speed and load regulation

• Industrial cogeneration and combined heat and power (CHP) installations

• Pipeline compressor stations with gas turbine and reciprocating engine control requirements

• Refinery and petrochemical facilities with turbine-driven process equipment

This concentration in power generation and oil and gas applications reflects Woodward's design focus on control hardware engineered for continuous-duty rotating machinery, where unplanned downtime carries significant operational and safety consequences.

Woodward Products and Solutions

Woodward industrial hardware at PLC Direct covers turbine controls, speed governors, overspeed protection systems, electro-hydraulic actuators, and electronic control platform modules used across installed Woodward-equipped turbine and engine control systems. The collection focuses on hardware that supports the maintenance and lifecycle continuity of existing Woodward installations.

Woodward Product Families

• 505 Steam Turbine Controls: The 505 is Woodward's digital governor for steam turbine applications with single or split-range actuators. The 505 series handles speed governing, load control, cascade and remote control, and auxiliary control for steam turbines across industrial and power generation applications. The 9907 series part numbers in the PLC Direct collection are confirmed 505 Digital Governor hardware, including the 9907-004US. The 505E is the enhanced variant with additional communication and sequencing capability.

• 2301 Electronic Load Sharing and Speed Controls: The 2301 series covers electronic load sharing and speed control for gas and diesel engine generator sets. The 2301A (part numbers in the 9905 range, including 9905-797US, 9905-020-P, 9905-007N) is one of Woodward's most widely deployed generator control products, providing isochronous speed control, load sharing between parallel generators, and frequency matching for generator paralleling applications.

• ProTech Overspeed Protection Devices: The ProTech series provides dedicated overspeed detection and trip protection for turbines and other rotating machinery where an independent safety shutdown system is required. ProTech devices monitor shaft speed continuously and initiate a shutdown trip when speed exceeds the preset overspeed limit, independent of the primary governor. The 9903 series part numbers in the PLC Direct collection (including 9903-059-ATC, 9903-041-0, 9903-003-D) are confirmed ProTech hardware.

• MicroNet Electronic Control Platform: The MicroNet is Woodward's modular programmable control platform for complex turbine, compressor, and engine control applications requiring custom control logic, multiple I/O types, and high-availability configurations. The MicroNet TMR (Triple Modular Redundant) variant provides fault-tolerant control for safety-critical applications. The platform covers chassis, power supplies, CPU modules, communication modules, analog and digital I/O modules, relay modules, and LINKnet I/O expansion modules. The 8915 series part numbers in the PLC Direct collection (including 8915-2032-HMC) are confirmed MicroNet hardware.

• Electro-Hydraulic Governors and Actuators: Woodward's mechanical and electro-hydraulic governor and actuator product line covers TG turbine governors, TGE turbine actuators, UG governors and actuators, VariStroke actuators, TM linear actuators, and CPC-II current-to-pressure converters. These devices convert electronic control signals into the mechanical hydraulic force required to position steam or fuel valves on turbines and engines. The 8570 and 8571 series part numbers in the PLC Direct collection (including 8571-259DC, 8570-846JK) are confirmed actuator and governor hardware.

• Gas Turbine Fuel Valves and Actuators: Woodward gas turbine fuel valve hardware includes the GS series gas fuel valve actuators (GS40, GS50), LQ series liquid fuel valve actuators, GSOV gas fuel shutoff valves, LSOV liquid fuel shutoff valves, and the DVP digital valve positioner. These components control fuel metering and shutoff at the combustion system level on gas turbines in power generation and oil and gas applications.

• ProAct Digital Speed Controls and Actuators: The ProAct series combines a digital speed control with an integrated actuator for engine governor applications on diesel and gas engines. ProAct units provide precise speed governing with digital setpoint control and are used on reciprocating engine generator sets and mechanical drive applications. ProAct part numbers appear in the 9905 and 9907 ranges within the collection.

• easYgen Generator Set Controls and Power Management: The easYgen series covers generator set controls and power management systems for parallel generator operation, automatic mains failure, synchronization, and load sharing. easYgen controllers are used on diesel and gas generator sets in standby and prime power applications across industrial facilities, data centers, and critical infrastructure.
