Masoneilan SVI™ FF Valve Positioner
Overview
The Masoneilan SVI FF is a digital valve positioner designed for FOUNDATION fieldbus H1 networks, delivering precise valve position control with full digital communication and diagnostics. Certified for FM, FMc, IEC, and ATEX installations in explosion-proof, intrinsically safe, and flame-proof configurations, it is suited to the most demanding process environments.
Powered from the H1 segment, the SVI FF implements the MAU 121 entity model and MAU 511 FISCO intrinsically safe profiles with power change on transmit, allowing direct connection to fieldbus segments in hazardous areas without additional power conditioning.
Engineering & Design
The positioner combines Masoneilan’s valve control expertise with the digital capabilities of the FOUNDATION fieldbus protocol, enabling remote configuration, calibration, and diagnostics over the same two-wire segment used for control. The NEMA 4X / IP66 enclosure provides weatherproof and corrosion-resistant protection for outdoor and harsh service installations.
With the FISCO-compliant MAU 511 profile, multiple SVI FF positioners can be connected to a single H1 segment in hazardous areas under the entity concept, simplifying fieldbus infrastructure while maintaining intrinsic safety. The device supports the full range of diagnostic data available to the control system, improving asset management and predictive maintenance.

Valve positioners are the final control element in most process control loops, and the Masoneilan SVI FF brings the diagnostic power of digital fieldbus communication to valve positioning. By combining FOUNDATION fieldbus connectivity with Masoneilan’s positioner heritage, the SVI FF provides precise positioning plus the asset management data that modern plants require.
For fieldbus valve control, the Masoneilan SVI FF valve positioner is a proven platform, and Seven Star LLC supplies the Masoneilan SVI FF valve positioner with certification documentation for hazardous area installations.
The Masoneilan SVI FF digital positioner is the FOUNDATION fieldbus version of the SVI II series and is mounted on the actuator of the control valve. The positioner is configured with the valve signature, the travel and the fail-safe action through the ValVue software, and the fieldbus segment supplies the power and the communication over the two-wire loop. The diagnostic data of the valve are read by the asset management system of the plant.
Why Seven Star LLC
Seven Star LLC supplies the Masoneilan SVI FF valve positioner for control valve projects across the Gulf, with full certification documentation and engineering support. Our specialists assist with fieldbus segment design, intrinsically safe profile selection, and integration with existing control systems.
We support valve automation programmes in power, refining, petrochemical, and oil and gas facilities, providing spares and technical guidance for Masoneilan products throughout the GCC.
Fieldbus Integration
The SVI FF is powered directly from the H1 segment and implements both the MAU 121 entity model and the MAU 511 FISCO profile, enabling installation on intrinsically safe fieldbus segments in hazardous areas. Configuration, calibration, and diagnostic data all travel over the same two-wire segment, reducing wiring and marshalling compared to analog positioners.
With FM, FMc, IEC, and ATEX certifications covering explosion-proof, intrinsically safe, and flame-proof installations, the positioner can be specified consistently across global projects.
