Product Description

Product Description

The Masoneilan SVI II AP (21123121 Series) Smart Valve Positioner represents the cutting edge of digital valve control technology from Baker Hughes, a global leader in industrial process control solutions. This microprocessor-based smart positioner combines exceptional precision, advanced diagnostics, and robust reliability to meet the demanding requirements of modern process automation systems.

Working Principle

The positioner operates as a closed-loop digital control system:
1.Input Signal Processing: Receives 4-20mA analog or digital signals (HART/Fieldbus/PROFIBUS)
2.Microprocessor Control: Advanced algorithms compare setpoint with actual valve position
3.Pneumatic Output: Precision I/P converter regulates air supply to actuator
4.Continuous Feedback: High-resolution position sensor ensures ±0.5% accuracy
5.Smart Diagnostics: Continuous monitoring of valve performance and health

Design Philosophy

The SVI II AP incorporates next-generation digital control technology in a rugged, field-proven package:
1.Industrial-grade aluminum housing with epoxy coating for corrosion resistance
2.Compact, modular design for easy installation and serviceability
3.IP66/IP67 protection against harsh environmental conditions
4.Intrinsically safe options for hazardous areas

 

The Masoneilan SVI II AP (21123121 Series) Smart Valve Positioner sets a new standard for digital valve control technology, combining unmatched precision, intelligent diagnostics, and robust reliability. Its advanced features deliver significant benefits across industries:
1. Superior process control through high accuracy and fast response
2. Reduced operational costs via predictive maintenance capabilities
3. Enhanced safety with SIL compliance and partial stroke testing
4. Seamless integration with modern digital control systems
