Product Overview
The Woodward 8200-507 Digital Valve Positioner (DVP) is a mission-critical actuator driver designed for gas turbine fuel and air valve control. It delivers high-current output and advanced control algorithms to drive Brushless DC (BLDC) and Linear Actuator Technology (LAT) motors with sub-millisecond response. Supplied 100% brand new and original, it ensures precise valve positioning, stable turbine governing, and optimized emission control.

Engineering Advantages
High-Power Actuation Output
Provides up to 5 kW peak power, enabling direct control of large fuel valves under high pressure without external amplifiers, simplifying system architecture.
Closed-Loop Precision Control
Processes resolver or encoder feedback internally to maintain highly accurate valve positioning, improving combustion efficiency and reducing emissions.
Deterministic Real-Time Response
High-speed digital processing ensures immediate reaction to load changes, minimizing frequency deviations and maintaining grid stability during transients.
Industrial Noise Immunity
Advanced EMI/RFI shielding protects against electrical noise from generators, drives, and switchgear, ensuring reliable signal integrity in harsh environments.
Rugged Environmental Design
Built for high-temperature and high-vibration environments, supporting reliable operation in unventilated cabinets up to 70°C.
FAQs
Does it support fail-safe operation?
Yes. The module can be configured to drive the valve to a predefined safe position (e.g., full close) upon signal loss or fault conditions.
Can it replace analog valve positioners?
Yes, but actuator compatibility (resolver/encoder feedback and wiring) must be verified before replacement.
How does it monitor actuator health?
Integrated diagnostics track parameters such as motor current, temperature, and position error, and report them to the control system for predictive maintenance.
Is this a refurbished unit?
No. All units are 100% brand new, supplied in original Woodward factory-sealed packaging with full documentation and traceability.
