Product Overview

The Foxboro SRD960/SRD991/SRD998 series intelligent electro-pneumatic valve positioners are precision control devices designed for industrial automation, specifically tailored for China's pneumatic bellows-sealed control valves. These smart valve controllers integrate HART communication protocols and advanced diagnostics, supporting both single/double-acting pneumatic actuators.

With ATEX/IECEx explosion-proof certification, they deliver accurate valve stroke control (8-260mm) and angular adjustment (up to 120°), making them ideal for demanding environments in petrochemical, power, and metallurgical industries.

Key Features
  • Intelligent Diagnostics: Built-in self-calibration and predictive maintenance via VALcare™ software for real-time valve health monitoring
  • Multi-Protocol Support: Compatible with HART 7, Profibus PA, and Foundation Fieldbus digital communication standards
  • Robust Protection: IP66 enclosure (SRD998 model) for operation in -40°C to 80°C temperatures and hazardous gas environments
  • User-Friendly Interface: Large graphical LCD display (backlight available in SRD998 AD) with multi-language support
  • Energy Efficiency: Automatic air pressure regulation (1.4-10 bar) reducing energy consumption by up to 30%
