Description
Masoneilan SVI II AP Digital Valve Positioner
Product Overview

The Masoneilan SVI II AP Digital Valve Positioner, including the SVI2-21123111 configuration, is a robust microprocessor-based device for precise pneumatic actuator control in hazardous industrial settings. With a 32-bit processor and HART protocol, it offers operable LCD and pushbuttons in certified explosive areas, enabling safe local configuration. The five built-in pressure sensors provide comprehensive diagnostics, while auto-tune and quick commissioning reduce setup time. Supporting single and double-acting actuators, the SVI II AP is essential for oil and gas, refining, and chemical plants, delivering safe, efficient valve operation.

Key Features
  • Hazardous Area Operation: LCD and buttons function in ATEX/FM/CSA zones.
  • Integrated Sensors: Five factory-calibrated pressure sensors for diagnostics.
  • Auto-Tune Setup: Fast commissioning with auto-stop methods.
  • HART Digital Interface: Remote access for monitoring and configuration.
  • Low Maintenance: Modular design for easy repairs.
  • Wide Compatibility: Single/double-acting pneumatic actuators.
  • Compact Enclosure: IP66 protection for harsh conditions.
  • Energy Efficient: Low air consumption for cost savings.
