Introduction to WOODWARD 8200-226
8200-226 Product Overview
The WOODWARD 8200-226 is a high-precision Servo Position Controller (SPC) module, a key product in the brand’s 8200 series dedicated to industrial valve and actuator control. It specializes in translating electrical control signals into precise mechanical positions, integrating adaptive feedback algorithms to ensure stable regulation of proportional and integral servo valves. Widely applied in gas turbine and steam turbine fuel control systems, it accurately adjusts fuel valve openings to match load demands, optimizing combustion efficiency and reducing emissions. Its rugged industrial design features anti-interference circuits and a compact housing, adapting to high-temperature and high-vibration environments in power plants and petrochemical facilities. Fully compatible with WOODWARD turbine controllers and DCS systems, it supports DeviceNet and 4-20mA signal protocols, enabling seamless integration for real-time monitoring and remote control.
