Masoneilan SVI3-21121212 Advanced Diagnostics IP66 Single Acting LCD Display 4-20 mA HART 7 Valve Positioner

Masoneilan SVI3-21121212 Digital Valve Positioner

The Masoneilan SVI3 (model configuration SVI3-21121212) is a third-generation digital valve positioner from Baker Hughes designed for precise control of pneumatic control valves. It combines advanced control algorithms with non-contact position sensing to deliver accurate, responsive, and reliable positioning performance.

Product Overview

This HART-based smart positioner supports single-acting fail-safe operation for both linear and rotary valves. Key advantages include simplified one-button SMART CAL setup and calibration, online valve diagnostics that continuously monitor valve health during operation, and improved pneumatic efficiency with reduced steady-state air consumption. The modular platform allows flexibility for different application needs while maintaining robust performance in industrial environments.

Technical Specifications

Application Industry

Widely used in power generation, refining, petrochemical, upstream and midstream oil & gas, and related process industries for control valve positioning in critical and general service applications.

Common Problems

Users may face challenges with calibration complexity, air consumption, or limited diagnostic visibility on older positioners. The SVI3 addresses these through single-button auto-calibration, improved air efficiency, and extensive online diagnostics that store data for trend analysis.

Replacement Models

Suitable as an upgrade or direct replacement for earlier Masoneilan SVI series positioners and comparable digital positioners on pneumatic control valves.
