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.

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).
Does it support double-acting actuators?
Standard models are single-acting; double-acting variants exist.
Can it run without a local display?
Yes – full remote operation via HART/DTM.
What is SmartRecovery?
A pressure-inferred control mode that keeps the process running when position sensing fails.
Is Online Valve Diagnostics standard?
Available on Advanced and Online Valve Diagnostics versions.
