Viking VXD Electric Release Deluge System for Rapid Fire Protection

The Viking VXD Pre-Trimmed Riser (PTR) series offers advanced fire protection solutions designed for rapid response and precision control in high-hazard environments. These systems are expertly engineered to safeguard critical infrastructure and valuable assets where accidental water discharge must be avoided or where high-speed suppression is paramount. By integrating the robust Model VXD Deluge Valve into a pre-assembled package, these systems ensure reliable performance and streamlined installation for professionals.

• Model VXD Deluge Valve: This high-performance, differential diaphragm valve features a single moving mechanism for superior reliability and easy resetting. It controls the water supply to system piping equipped with open sprinklers and/or spray nozzles, keeping the pipes empty until activation.
• Monitored Release Solenoid: Includes a monitored electric solenoid that provides an NFPA 13 compliant solution for continuous supervision of the system’s operational status. This feature ensures that if the solenoid is removed or disconnected, a visual and audible signal is generated at the control panel, enhancing system integrity.
• Pre-Trimmed Riser (PTR) Package: The system comes fully assembled and ready to install, including the VXD deluge valve with trim, a riser check valve, water supply control valve, and pressure gauges. This pre-assembled design significantly reduces installation complexity and labor costs.
• Durable Construction: Crafted from high-grade ductile iron with galvanized piping and groove/groove connections, providing exceptional corrosion resistance and mechanical strength.
• Supervised Pneumatic Pressure: Preaction models utilize pressurized air or nitrogen to monitor piping integrity, triggering "low air" alarms to identify leaks before water enters the system, offering an added layer of protection against accidental discharge.
• Certified Performance: These systems are UL Listed and FM Approved, meeting stringent industry safety and performance standards.
• Versatile System Configurations: Available in Deluge, Single Interlock, and Double Interlock Preaction configurations to provide tailored protection for diverse applications:
  • Deluge Systems: Ideal for high-risk areas like chemical plants and aircraft hangars, providing immediate, simultaneous water discharge across the entire hazard area upon detection.
  • Single Interlock Preaction: Perfect for water-sensitive areas such as data centers and museums, admitting water into the piping only upon activation of a fire detection system.
  • Double Interlock Preaction: Features a dual-trigger mechanism requiring both an electrical detection event and a loss of pneumatic pressure, offering the highest level of protection against accidental discharge in environments like cold storage or archives.

Whether protecting a power plant or a telecommunications room, the Viking VXD PTR series delivers peace of mind through its dependable design and innovative monitoring features. The pre-assembled design significantly reduces labor costs and installation complexity while ensuring your fire suppression system is always ready when it matters most.
