IMI STI SHP SI00ASSAU is a high-performance variant from the SHP series (Smart High-Performance Positioner) by IMI STI, Italy. It is a state-of-the-art, high-capacity digital-pneumatic valve positioner designed as a valve care controller, succeeding and surpassing the earlier FasTrak (FT) series. With the highest flow rate on the market, patented control algorithms, and advanced diagnostics, it delivers ultra-fast response, exceptional dynamic performance, and precise valve positioning for critical industrial processes.
Product Overview
The IMI STI SHP SI00ASSAU is a smart, high-precision digital-pneumatic positioner engineered for demanding valve control applications. It features superior flow capacity, patented logic for minimal stroking times, and real-time diagnostics (online/offline). Replacing traditional positioners, it ensures reliable, high-speed actuation with low air consumption and vibration-resistant contactless feedback (standard or optional remote sensor up to 20m). It supports HART 7 communication, USB, FDI drivers, and remote software configuration, making it ideal for modern valve care and process optimization.
