Product Overview

The Masoneilan SVI2-21123121, SVI2-22113121, and SVI2-21123111 Intelligent Digital Valve Positioners are advanced electro-pneumatic instruments designed for accurate positioning and control of pneumatic valve actuators in industrial process systems. Manufactured by Masoneilan, a Baker Hughes brand, these SVI II AP Series positioners combine microprocessor-based control, HART digital communication, and contactless magnetic position sensing to deliver reliable valve positioning. Their 4–20 mA electrical input enables integration with distributed control systems for precise flow and pressure regulation.

The SVI2-21123121 features single-acting pneumatic operation, an integrated LCD display, position retransmission, and limit switch outputs. The SVI2-22113121 provides double-acting pneumatic control without a local display, while the SVI2-21123111 offers single-acting operation with an LCD display but without the optional feedback board. All three configurations support standard valve diagnostics, automatic calibration, and reliable industrial process control. They are suitable for oil and gas processing, chemical manufacturing, petroleum refining, power generation, water treatment, and industrial valve automation.

// FAQs

Questions about this part?

Our engineers can confirm fit before you order. Contact support.

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.
