Product Overview
The Masoneilan SVI2-31123121 Intelligent Valve Positioner is an advanced electro-pneumatic control instrument designed for precise positioning of pneumatic valve actuators in industrial process systems. Manufactured by Masoneilan, a Baker Hughes brand, this SVI II AP Series positioner combines microprocessor-based control with HART digital communication to deliver accurate valve positioning and reliable process performance. Its 4–20 mA control signal supports seamless integration with distributed control systems and industrial automation equipment.
The SVI2-31123121 features advanced diagnostic capabilities, a local LCD display with pushbuttons, contactless magnetic position sensing, and a single-acting pneumatic configuration. Its explosion-proof design supports suitable hazardous-area installations, while automatic calibration simplifies commissioning and maintenance. It is suitable for oil and gas processing, chemical manufacturing, power generation, petroleum refining, and industrial valve automation.

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.
