Product Overview
The Masoneilan SVI2-22113111 (SVI II AP) Digital Valve Positioner is an advanced, high-performance intelligent electro-pneumatic device designed to provide precise positioning and digital communication for industrial pneumatic control valves. Manufactured by Baker Hughes under the Masoneilan brand, this positioner utilizes solid-state non-contact Hall-effect position-sensing technology, eliminating mechanical linkages and reducing physical wear to deliver sustained measurement accuracy and operational reliability.
Engineered with a single-acting pneumatic relay and an explosion-proof aluminium enclosure, the SVI2-22113111 operates on a standard 4–20 mA input loop with bidirectional HART communication protocol. It features an integrated LCD display with local push buttons for rapid autotuning, calibration, and real-time field diagnostics. Compatible with both linear and rotary pneumatic actuators, this smart positioner is widely deployed in oil and gas refineries, chemical manufacturing, power generation facilities, and process automation plants requiring continuous valve diagnostics and high-precision flow modulation.

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.
