The Masoneilan SVI3 is a high-performance, HART 7 digital valve positioner designed for precise control of pneumatic control valves in demanding industrial environments. It combines non-contact magnetic (Hall-effect) position sensing, advanced autotuning, extensive diagnostics (including Online Valve Diagnostics and SmartRecovery), and optional local LCD/pushbutton interface. Suitable for both rotary and reciprocating valves, air-to-open or air-to-close actuators, it supports single-acting operation with robust aluminum or 316L stainless-steel housing rated IP66 / NEMA 4X.

• Non-contact Hall-effect position sensing (no shaft penetration, sealed electronics)
• Extreme accuracy (±0.5% full span) with autotuning and user-adjustable response
• SmartRecovery mode – pressure-based control when position feedback fails
• Online Valve Diagnostics with 1-year onboard KPI storage (friction, stick-slip, obstruction, cycling, RMS error, etc.)
• Optional LCD + four pushbuttons for local configuration/calibration
• Options board: position retransmit (4-20 mA), digital input/output switches, remote position sensor, PV input
• HART 7 communication; full DTM and EDD support
• Tight shut-off, split-range, custom characterization, high/low position limits
• Hazardous-area approvals (ATEX, IECEx, USA, Canada, etc.)

Oil & gas, refining, petrochemical, power generation, chemical processing, marine, and any process requiring high reliability, diagnostics, and precise valve positioning under harsh conditions (including natural-gas service with ≤20 ppm H₂S).
