Viking Electric Relief Flow Control Valve for Fire Systems

The Viking Electric Relief Flow Control Valve functions as a quick-opening, differential diaphragm flood valve engineered for commercial and industrial fire protection assemblies. It integrates seamlessly into deluge and pre-action systems, utilizing an automated solenoid actuator to relieve pressure from the control chamber and enable rapid water release during emergencies. A spring-loaded floating clapper keeps downstream piping dry until active suppression is triggered.

This valve satisfies strict installation and life safety requirements governed by NFPA 13 for fire sprinkler system design and implementation. By automatically releasing excess pressure before system failures occur, it prevents costly equipment damage and ensures reliable response capability in demanding industrial environments.

• Ductile Iron Body: Crafted from high-grade, corrosion-resistant ductile iron to deliver structural strength and long-term service life in harsh operating conditions.
• Solenoid Actuation: Features an integrated solenoid actuator that opens to relieve control chamber pressure, automating system responsiveness and connecting directly with existing fire alarm networks.
• Differential Diaphragm Design: Utilizes a spring-loaded floating clapper mechanism to maintain dry downstream piping until the system activates.
• Flexible Orientation: Supports both horizontal and vertical installation orientations to accommodate compact layouts and diverse piping configurations.
• External Monitoring: Equipped with an external control mechanism and visible trim piping to monitor water relief and mitigate overpressure risks.

Verify all local Authority Having Jurisdiction (AHJ) requirements and consult the manufacturer's technical data sheets before commencing installation or system layout.
