Product Overview
The Masoneilan SVI2-22123121 Intelligent Digital Valve Positioner is designed for precise positioning and automated control of pneumatic valve actuators in industrial process systems. Manufactured under the Masoneilan brand by Baker Hughes, this smart electropneumatic positioner uses a standard 4–20 mA electrical input signal with HART digital communication to regulate pneumatic output pressure and maintain accurate valve positioning. Its double-acting configuration supports controlled air delivery to both sides of compatible pneumatic actuators, ensuring responsive valve movement, stable flow regulation, and reliable performance in demanding industrial environments.
Part of the Masoneilan SVI II AP series, the SVI2-22123121 features microprocessor-based control technology, non-contact magnetic position sensing, standard diagnostic capabilities, and an integrated LCD display with pushbuttons for convenient configuration and monitoring. Its position retransmission and limit switch functions support valve position feedback and process monitoring, while automatic calibration simplifies installation and commissioning. With a durable aluminium housing and industrial-grade pneumatic components, this positioner is suitable for oil and gas processing, chemical manufacturing, power generation, water treatment, and industrial valve automation applications.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
