Product Overview

The Foxboro SRD960 + Danfoss EV220B is a high-performance on/off control solution integrating the intelligent SRD960 universal positioner with the robust EV220B 2/2-way solenoid valve. The SRD960 provides HART 7 communication, auto-tuning, and full diagnostics, while the EV220B delivers 100 ms response and up to 40 bar pressure handling. With Ex d IIC T6 explosion-proof certification and IP66/67 enclosure, this pre-engineered combo ensures fail-safe operation in critical shutdown, blowdown, and batching applications. The plug-and-play design reduces commissioning time by 70% and enables predictive maintenance through ValveLink integration.

Key Features
  • HART 7 Diagnostics: SRD960 with position, stroke, and response monitoring.
  • 100 ms Response: EV220B for fast shut-off.
  • Fail-Safe Operation: Spring-return or double-acting configurations.
  • Ex d IIC T6: Flameproof for Zone 1 hazardous areas.
  • Auto-Tuning: One-button setup via SRD960 local display.
  • High Flow Cv 20: Up to 1.5" line size.
  • ValveLink Ready: Predictive alerts for seat wear and stiction.
  • IP66/67: Dust-tight and water immersion resistant.
