Vxd Series Deluge and Preaction Systems, Monitored

The Viking VXD series offers high-performance fire protection solutions designed for demanding commercial and industrial environments. Built around the innovative Model VXD deluge valve—a quick-opening, differential diaphragm flood valve with a single moving mechanism—these systems provide reliable water control for both deluge and preaction configurations. Whether protecting high-hazard areas or water-sensitive assets, these systems are engineered to deliver precise fire suppression while minimizing the risk of accidental discharge.

• Advanced System Configurations: Available in Deluge, Single-Interlocked, and Double-Interlocked Preaction setups. Deluge systems provide immediate, simultaneous water discharge for rapid fire spread areas, while Preaction systems offer tiered activation layers to safeguard environments where accidental water damage could be catastrophic.
• Robust Release Mechanisms: Features sophisticated electric and pneumatic release options. The electric release integrates seamlessly with fire detection panels and solenoid valves, while pneumatic actuators monitor supervisory air or nitrogen pressure within the piping to ensure system integrity.
• Double-Interlock Technology: For maximum security, double-interlocked systems require two independent events—typically the activation of an electric detection system and a loss of supervisory pressure—before water enters the piping, providing an essential safeguard for data centers, museums, and cold storage.
• Flexible Trim Options: Available in both pre-trimmed riser assemblies and loose trim configurations. Pre-trimmed units are factory-assembled and tested to streamline installation and reduce on-site labor, while loose trim provides the flexibility needed for custom system layouts.
• Corrosion-Resistant Construction: Components are crafted from high-quality materials, including brass and galvanized steel, to ensure long-term durability and resistance to harsh environmental conditions.
• Comprehensive Monitoring and Compliance: Systems include monitored release solenoids and supervisory pressure switches to provide continuous oversight. These configurations are designed to be NFPA 13 and NFPA 72 compliant, ensuring adherence to rigorous fire safety codes and industry standards.
• Certifications: Most assemblies are UL Listed and FM Approved, guaranteeing performance integrity and reliability under critical conditions.

By combining rapid response times with advanced supervision, these VXD systems protect both life and property. They are ideal for high-risk applications such as aircraft hangars, chemical plants, archival vaults, and laboratories, offering peace of mind through proven technology and robust engineering.
