Schneider Foxboro Control Valve Positioner SRD960 SRD991 SRD998 and Asco Danfoss Solenoid Valve for Precision Flow Control

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.

• 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.

• Emergency Shutdown (ESD): Rapid isolation in refineries.
• Blowdown Systems: Depressurization in offshore platforms.
• Batch Sequencing: Chemical reactor fill/drain.
