The Masoneilan SVi1000 is a digital electro-pneumatic valve positioner designed for single-acting pneumatic control valves. It receives a 4-20 mA position setpoint signal, compares it with valve position feedback from a non-contact magnetic sensor, and adjusts actuator pressure for accurate positioning. The unit supports HART communication for local or remote configuration and diagnostics.
This positioner features a user-friendly one-button-one-function local interface with LEDs for simple setup and calibration. It uses a robust non-contact magnetic travel sensor suitable for both linear and rotary valves. The industrial aluminum housing provides IP66 / NEMA 4X protection. Optional features include solid-state switches, position retransmit, and integrated magnet. Automated commissioning and preset configurations help reduce startup time, while built-in diagnostics support cycle counts, step tests, and system health monitoring.

Used in process industries including oil and gas, chemical processing, power generation, refining, and general industrial control for accurate positioning of single-acting pneumatic control valves.
Users may encounter issues with complex initial setup of older positioners or limited diagnostic visibility. The SVi1000 addresses these through simplified local interface buttons, automated commissioning functions, non-contact sensing that reduces wear, and HART-based remote diagnostics.
Suitable as a replacement or upgrade for earlier Masoneilan SVI series positioners and other conventional or digital single-acting positioners requiring HART communication and non-contact feedback.
We supply genuine Masoneilan (Baker Hughes) positioners and provide practical support for correct selection and application matching in process control systems.
Typical production and delivery time is 6-8 weeks.
Please provide details on valve type (linear or rotary), actuator specifications, required options (switches, retransmit, gauges), hazardous area needs, and quantity for a tailored quotation.
