Neles™ ValvGuard™ VG9000 Intelligent Safety Solenoid for ESD and ESV Valves

The VG9000 is a high-performance intelligent safety solenoid designed for emergency shutdown (ESD) and emergency venting (ESV) valve applications. It combines advanced diagnostics, predictive maintenance capabilities, and partial stroke testing (PST) to enhance plant safety and reduce operational costs.

Key Features:

• Partial Stroke Testing (PST): Automatic or manual PST functionality helps verify valve operability without full activation, reducing the risk of spurious trips and costly shutdowns.
• Continuous Diagnostics: The diagnostics module operates independently from the safety function, ensuring uninterrupted data collection—even during emergency trips.
• Predictive Maintenance: Real-time monitoring and graphical data logging allow early detection of potential valve failures, enabling proactive maintenance planning.
• High Pneumatic Capacity: Eliminates the need for additional instrumentation in most cases, with a max exhaust capacity of 700 Nm³/h (Cv 6.4).
• Flexible Communication: Supports HART (VG9000H) and FOUNDATION Fieldbus (VG9000F) protocols.
• Robust Construction: Available in anodized aluminum or stainless steel, suitable for harsh and offshore environments.
• SIL 3 Certified: Compliant with IEC 61508, certified by TÜV Rheinland for use in safety-critical applications.

VG9PST Variant

The VG9PST model enhances protection against spurious trips when used with an external solenoid valve, offering additional reliability and minimizing unnecessary plant interruptions.

Applications:

• Oil & gas
• Chemical processing
• Power generation
• Offshore installations
• Any safety-critical valve automation scenario
