Viking VK320 K5.6 Quick Response Horizontal Sidewall Fire Sprinkler

The Viking VK320 K5.6 Quick Response Horizontal Sidewall Fire Sprinkler provides specialized fire protection for commercial, industrial, and storage facilities where ceiling-mounted units are impractical. This high-performance sprinkler is engineered for optimal placement in areas such as corridors, aisles, and rooms with unique architectural designs. By delivering rapid and targeted fire suppression, it ensures reliable protection in challenging layouts and significantly reduces the risk of fire spread.

• Quick Response Activation: Equipped with a sensitive fusible element assembly, this sprinkler activates swiftly upon detecting heat, typically using a metallic link that melts at a specific temperature. This rapid response is crucial for containing fires in their earliest stages, enhancing occupant safety and minimizing property damage.
• Horizontal Sidewall Design: Specifically designed for installation on walls or structural elements, the VK320 discharges water outward and downward in a quarter-spherical pattern. This design effectively covers the area below and in front of the sprinkler, making it ideal for spaces where ceiling installations are not feasible or would detract from aesthetics.
• High-Pressure Compatibility: Engineered to operate efficiently under high-pressure water systems, this sprinkler features a maximum working pressure of 250 PSI (17 bar). This ensures reliable water distribution in large-scale or complex facilities.
• 5.6 K-Factor: With a K-factor of 5.6, this sprinkler provides consistent and focused fire suppression. The K-factor is a numerical value representing the sprinkler head's orifice size and flow characteristics, defining the precise water flow required for effective fire protection system design at a given pressure.
• Durable Construction: Manufactured from corrosion-resistant materials, including a brass frame casting and a phosphor bronze deflector, these sprinklers are built for longevity. The robust design maintains reliability in harsh environments and exposed installations over time.
• Compliance and Certification: The Viking VK320 is UL Listed, FM Approved, and fully compliant with NFPA 13 standards. This meets rigorous safety regulations for professional fire protection systems and ensures it adheres to design and installation guidelines for sidewall standard spray sprinklers.

Trusted by fire protection professionals, the Viking VK320 is a critical component for tailored fire defense. Its combination of rapid response times and high-pressure capabilities makes it a reliable choice for protecting both assets and lives in demanding conditions. Whether protecting exterior walls or narrow corridors, this sprinkler delivers the performance necessary for comprehensive safety across diverse environments.
