Description
Woodward MCDGV4-2A0AA
Technical Specifications
- Type: Microprocessor Control Valve.
- Actuation: Digital servo or stepper motor.
- Feedback: Integrated position transducer.
Functional Features
- Digital Precision: Eliminates hysteresis and drift associated with analog valves.
- Self-Diagnostics: Continuous monitoring of valve health and position.
- Fast Response: High-bandwidth control for rapid load changes.
Application Scenarios
Used in gas turbines, steam turbines, and compressor anti-surge control systems.
Performance Parameters
- Linearity: High-precision flow characteristic.
- Resolution: Fine incremental positioning.
Material Composition
Stainless steel wetted parts with high-performance seals.
Structural Characteristics
Integrated electronics and actuator in a compact package.
Working Principle
Receives a digital command from the turbine controller, processes it internally, and drives the actuator to the exact position, continuously verifying with internal feedback.
Installation Requirements
Align valve with piping to prevent stress. Connect power and signal cables with proper shielding.
Precautions for Use
Do not force the valve manually. Calibrate position feedback after installation.
