Masoneilan SVI3-21121212 SVI3-21121112 Smart Valve Controller Single Acting HART Pneumatic Actuator Valve Positioner

The Masoneilan SVI3 is the third-generation digital valve positioner from Baker Hughes, designed for accurate and reliable control of single-acting pneumatic control valves. The configuration SVI3-21121112 belongs to this series and utilizes advanced control algorithms together with field-proven non-contact magnetic position sensing to deliver responsive performance in industrial process applications.

Product Overview

This HART 7 digital positioner features SmartCal one-button setup and calibration for simplified commissioning. It supports both linear and rotary valves with a universal mounting approach. Online valve diagnostics continuously monitor health, with the ability to store diagnostic data for extended periods to help identify issues before they affect operations. Low-bleed pneumatics reduce steady-state air consumption while maintaining strong control response. An optional local graphical display with pushbuttons enables configuration and monitoring in the field, including hazardous areas. The unit is built for durability in demanding environments and integrates with major control systems via HART communication and supporting software tools such as ValVue.

Technical Specifications

Application Industry

Applied in power generation, refining, petrochemicals, oil and gas (upstream, midstream, and downstream), chemical processing, and general industrial process control for precise positioning of pneumatic control valves.

Common Problems

Users of earlier positioners often face lengthy calibration procedures, higher air consumption, limited diagnostic insight while the valve is in service, or restricted temperature capability. The SVI3 addresses these through one-button SmartCal, reduced air bleed, continuous online diagnostics with data storage, and an extended low-temperature operating range.

Replacement Models

Serves as a modern upgrade or replacement for previous Masoneilan SVI series positioners (such as SVI II or SVi1000) and other conventional or digital single-acting positioners requiring improved diagnostics, lower air consumption, and HART 7 communication.
