Auto Tune Digital Valve Positioner Masoneilan SVI2 AP Diagnostics 4-20mA Non-contact Position Sensing Valve Positioner

Masoneilan SVI2 (SVI II AP) Digital Valve Positioner

The Masoneilan SVI II AP is an advanced digital valve controller that delivers high-performance positioning for pneumatic control valves. It operates on a two-wire 4-20 mA signal with bi-directional HART communication and incorporates a field-proven non-contact position sensor for reliable feedback.

Product Overview Designed for universal application, the SVI II AP supports both linear and rotary valves as well as single-acting and double-acting actuators. The local explosion-proof LCD and pushbuttons allow configuration and calibration even in certified hazardous environments. Auto-commissioning functions and modular construction simplify installation and future upgrades. Real-time diagnostics, including pressure sensing and valve signature analysis, help monitor valve and actuator health. High-flow versions are available to handle larger actuators without additional accessories.

Technical Specifications

Application Industry Widely applied in process control environments such as chemical plants, petrochemical facilities, power stations, and oil & gas installations requiring accurate and diagnostic-capable valve positioning.

Common Problems Typical issues with conventional positioners include mechanical sensor wear, difficult hazardous-area operation, and limited diagnostic data. The SVI II AP reduces these concerns through sealed non-contact sensing, certified local interface, and advanced diagnostic capabilities accessible via HART or ValVue software.

Replacement Models An effective modern replacement for legacy Masoneilan SVI II or earlier digital/analog positioners, as well as competitive single- and double-acting digital positioners.
