GE Electric | DS200SHVMG1AGE | Servo Hydraulic Valve Monitor Card
Product Description:
The GE DS200SHVMG1AGE is a Servo Hydraulic Valve Monitor Card for Speedtronic Mark V turbine control systems. It provides precise monitoring and conditioning of servo valve feedback signals (LVDT/RVDT) from hydraulic actuators controlling critical turbine components (e.g., governor valves, inlet guide vanes), enabling real-time position validation and failure detection.

Key Features:
- Dual-Channel Redundancy – Parallel monitoring for critical valve actuators.
- Advanced Diagnostics – Real-time detection of servo valve coil/feedback faults.
- Fail-Safe Design – Triggers turbine shutdown on critical signal loss.
- Noise Immunity – EMI/RFI filtering for high-electrical-noise environments.
- Hot-Swap Capability – Replaceable during turbine operation (redundant systems).
- SIL-3 Compliance – Certified for safety-critical protection systems.
Primary Function & Purpose:
Converts raw LVDT/RVDT signals from hydraulic actuators into calibrated position feedback for turbine control logic. Monitors signal integrity to prevent hazardous valve malfunctions (e.g., overspeeding) by triggering protective trips upon fault detection.
Typical Applications & Use Cases:
- Governor Valve Control – Steam/gas turbine load regulation.
- Inlet Guide Vane (IGV) Positioning – Compressor surge prevention.
- Bypass Valve Actuation – Fast-response pressure control.
- Hydraulic Pitch Systems – Wind turbine blade angle adjustment.
- Safety Shutdown Systems – Emergency valve closure monitoring.
Application Field:
Deployed in critical hydraulic control loops within:
- Power Plants: Combined-cycle (CCPP), steam turbine, hydroelectric.
- Aeroderivative Turbines: Mobile power generation.
- Oil & Gas: Turbine-driven compressors/pumps.
- Industrial Turbomachinery: Compressor stations, mechanical drives.
