DPU-MR
Key Features & Advantages
The **Metso DPU-MR** is a smart valve positioner designed for precise control of rotary valves in critical process applications. Features auto-calibration (AutoTune™) for rapid setup and adaptive control algorithms to minimize hysteresis. Integrated diagnostics monitor valve health, including friction, packing wear, and seat leakage. Compatible with Neles® Valve Manager software for real-time performance analysis and predictive maintenance. Supports HART/Fieldbus communication for integration with DCS/PLC systems.
Robust IP66/IP67 enclosure resists dust, moisture, and corrosive environments. SIL 2 certified for safety-critical applications. Optional explosion-proof (Ex d) housing for Zone 1/21 hazardous areas.
Applications
**Oil & gas** pipelines for choke valve control. **Chemical plants** for reactor feed valves. **Power generation** (steam turbine bypass valves). **Pulp & paper** for stock flow regulation. **Water treatment** in throttling and shut-off applications. Also used in **pharmaceutical** and **food & beverage** industries.
