Description

Meta Description & Product Overview


The Foxboro SRD991 Intelligent Valve Positioner is a high-performance, microprocessor-based digital valve controller designed for demanding industrial process applications. Offering compatibility with HART® 7 and Foundation Fieldbus™, the SRD991 ensures accurate valve positioning, smart diagnostics, and predictive maintenance capabilities. Manufactured by Schneider Electric (formerly Invensys Foxboro), it supports both linear and rotary actuators and features auto-calibration, IP66 protection, and a wide operating temperature range, making it an ideal solution for industries such as oil & gas, power generation, chemicals, and water treatment.



Key Features & Benefits


  • ✅ High Precision Positioning – Linearity better than ±0.2%, repeatability ±0.1%

  • ✅ Dual Protocol Support – Communicates via HART 7 or Foundation Fieldbus

  • ✅ Advanced Diagnostics – Continuous monitoring of valve stroke, friction, air supply, and actuator performance

  • ✅ Auto Setup & Calibration – Simplified commissioning with push-button or remote configuration

  • ✅ Explosion-Proof Design – Certified for hazardous area use: ATEX, CSA, FM, IECEx

  • ✅ Flexible Mounting – Supports both linear and rotary actuators with NAMUR compliance

  • ✅ Durable Housing – IP66-rated, corrosion-resistant aluminum alloy enclosure

  • ✅ Integrated LCD Display – Intuitive user interface with multi-language support
