METSO D201925L Product Details
1. Product Overview
The METSO D201925L is a high-reliability intelligent valve positioner engineered for industrial valve control in oil & gas, mining, and water treatment sectors. It serves as a critical link between process controllers and control valves, focusing on precise valve stem positioning, real-time status feedback, and adaptive control—essential for optimizing process flow, reducing energy waste, and ensuring operational safety in harsh industrial environments.
Integrating advanced digital control algorithms and multi-protocol communication, it adapts to diverse valve types (e.g., globe, butterfly valves) and process conditions. Compatibility with Metso’s Neles valve series and standard industrial control systems makes it a versatile component for modern process automation.

3. Product Specifications & Features
3.1 Core Specifications
The METSO D201925L is optimized for precise valve control, with ±0.1% full-scale accuracy and ≤0.2-second response time ensuring fast and stable adjustment of process flow (e.g., chemical injection systems). It supports both linear and rotary valves, covering stroke ranges from 10 mm to 100 mm and torque up to 500 N·m—adapting to most industrial valve applications.
The 4–20 mA input/output and HART 7.0 protocol enable analog control and digital diagnostics, allowing remote monitoring of valve position, air supply pressure, and fault status. The VDI/VDE 3845 standard mounting ensures quick installation and replacement, reducing downtime during maintenance.
3.2 Key Features
-
Superior Control Precision: ±0.1% accuracy and fast response time minimize process fluctuations, improving product quality and yield.
-
Dual Valve Compatibility: Supports both linear and rotary valves, eliminating the need for separate positioners for different valve types.
