Description
Emerson 1C31197G01
Technical Specifications:
- Brand: Emerson (Ovation)
- Model: 1C31197G01
- Product Type: Valve Positioner Electronic Module
- Function: Closed-loop valve positioning
Functional Features:
- Precise Positioning: Eliminates valve hysteresis and stiction for accurate control.
- Auto-Calibration: Supports automatic tuning to match specific valve characteristics.
- Diagnostic Feedback: Reports valve position, travel deviation, and actuator health.
Application Scenarios:
Critical in steam turbine control, boiler feedwater regulation, and chemical reactor feed systems.
Performance Parameters:
- Positioning Accuracy: Sub-percent accuracy
- Response Speed: Fast dynamic response to setpoint changes
Material Composition:
Ruggedized electronics designed to withstand vibration and temperature fluctuations near valve actuators.
Structural Characteristics:
Interfaces directly with Ovation I/O bases and field valve actuators.
Working Principle:
Compares the commanded position with actual valve stem feedback, adjusting the output signal to drive the actuator until the error is eliminated.
Installation Requirements:
Mount securely near the valve actuator. Ensure feedback linkage is properly aligned and calibrated.
Usage Precautions:
Perform a full stroke calibration after installation. Verify actuator air supply pressure is within specifications.
