Technical Specifications 24VDC power supply, proportional drive signal output and LVDT feedback input. Operating temperature: -40℃ ~ +70℃.
Functional Features Valve command processing, proportional drive output, LVDT position feedback, valve position fault alarm, stroke limiting.
Application Scenarios Steam turbine governing valve control, industrial steam turbine generator control systems.
Performance Parameters High linearity of valve control, precise position holding, fast response to load changes.
Structural Characteristics Rack pluggable heavy-duty control module, valve status and fault indicators.
Working Principle The module compares the target valve opening command with real-time LVDT position feedback, adjusts the drive output continuously to push the steam valve to the required opening position.
Installation Requirements Lay shielded cables for valve feedback, keep module away from high-temperature steam piping.
Usage Notes Calibrate valve stroke after installation, regularly inspect hydraulic actuator and sensor wiring.
