Azbil AVP70_ Series Smart Valve Positioner | HART & Foundation Fieldbus, Advanced Diagnostics

The Azbil AVP70 (AVP701, AVP702, AVP703) Series represents the cutting edge of smart valve positioning technology. This intelligent, electro-pneumatic positioner is engineered to provide precise control and unparalleled diagnostic capabilities for your valve assets. It is designed to be universally compatible, working seamlessly with control valves from any major brand worldwide, which simplifies upgrades and standardizes your inventory.

Purchase details

At the heart of its innovation is an integrated pressure sensor system. This system continuously monitors supply air pressure, output pressures, and internal nozzle backpressure. The data feeds an advanced control valve diagnostic algorithm, enabling predictive maintenance by detecting issues like stiction, hysteresis, and air leaks early. This proactive approach significantly enhances operational safety, plant stability, and reduces unplanned downtime.

Equipped with a Local User Interface (LUI) featuring an LCD and buttons, the AVP70_ allows for full configuration, calibration (auto-setup), and diagnostics directly at the device—even in hazardous explosive environments. Its energy-saving control relay optimizes air consumption, improving efficiency. For system integration, it supports industry-standard tools like EDDL, DTM, and Plug-In for Valstaff, ensuring easy connection to your plant management systems.

Key Features & Benefits

Universal Valve Compatibility: Works with any brand of control valve, offering exceptional flexibility for global operations.
Advanced Predictive Diagnostics: Built-in pressure sensors and diagnostic algorithms help identify valve health issues before they cause failures.
Safe Hazardous-Area Operation: The local user interface (LUI) is designed for safe use in explosive atmospheres, allowing on-site configuration and monitoring.
Dual Communication Protocol Support: Offers models compatible with both the widely adopted HART® protocol and the high-performance FOUNDATION™ Fieldbus, fitting into various digital architecture needs.
Enhanced Control & Energy Efficiency: Features a control relay for improved responsiveness and lower air consumption, contributing to operational cost savings.
