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.

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.
Why Buy From Us We provide authentic Masoneilan SVI II AP controllers and support customers with technical guidance for successful integration into existing control systems.
