The Viking VK124 K5.6 High-Pressure Upright Fire Sprinkler is engineered for commercial and industrial wet pipe fire protection systems requiring robust performance under elevated pressures. Installed in an upright orientation above the piping, this sprinkler projects water upward against a deflector to distribute a uniform, dome-shaped pattern over the hazard area. This configuration prevents debris and ice accumulation on the head, making it reliable for open-ceiling commercial spaces, manufacturing plants, and high-ceiling warehouses.

Designed to comply with NFPA 13 standards for light and ordinary hazard occupancies, the VK124 satisfies stringent life safety and property protection mandates. It features a thermosensitive glass bulb containing expanding liquid that shatters at precise high temperatures to initiate rapid water release. UL Listed and FM Approved, this high-pressure sprinkler meets commercial compliance requirements for pressure tolerance, corrosion resistance, and structural integrity.

• High-Pressure Rating: Rated for a maximum working pressure of 250 psi (17 bar) to support demanding industrial fire suppression systems.
• K-Factor 5.6: Delivers a balanced discharge coefficient to optimize water flow rate relative to pressure in compliance with NFPA 13.
• Upright Deflector Design: Positions the deflector above the pipe assembly to throw water upward and establish a uniform, dome-shaped distribution pattern.
• Precision Thermal Activation: Utilizes a thermosensitive glass bulb that shatters at specific temperatures to trigger rapid system response.
• Standard Thread Connection: Integrates easily into new or existing piping using a standard 1/2-inch National Pipe Taper (NPT) threaded connection.
• Corrosion-Resistant Options: Constructed from premium metal alloys with available polyester and Electroless Nickel PTFE (ENT) coatings for harsh environments.

Contractors and facility managers must verify local Authority Having Jurisdiction (AHJ) requirements, specific temperature ratings, and spacing rules before installation. Always consult the official manufacturer documentation to ensure correct engineering and code compliance.
