Woodward 8200-226 Servo Position Controller

This servo position controller handles precise valve positioning tasks in demanding industrial environments. Designed for both proportional and integrating servo valves, it accepts DeviceNet or 4-20mA position demand signals while maintaining consistent performance across fluctuating conditions.

Found in critical applications like turbine control systems and process automation setups. We frequently handle related models including the 8521-0312 UG-10D digital controller, 9907-167 governor systems, and TG-13 (8516-038) actuators. Common installations include power generation facilities and hydrocarbon processing plants requiring precise valve modulation.

Handles dual AC feedback devices or single DC sensor inputs for redundant operation. Configuration through Windows-based software allows remote tuning adjustments without physical access. Built-in key lock prevents unauthorized modifications while maintaining NEMA-1 enclosure compatibility.

Survives harsh environments (-15°C to +60°C) with standard DeviceNet integration. Actual field tests showed 0.1% position accuracy drift over 12-month periods in vibration-prone installations. For instance, one offshore platform reported 30% faster response times when replacing legacy systems with these controllers.
