Overview
The Viking™ VK795 C-1 Window Sprinkler (Part Number 01325BF) is a powerful, open-type sprinkler built for deluge fire protection systems. It is specifically designed to protect windows, walls, and roofs from exposure fires and radiant heat from nearby structures or equipment. When the system is activated, the sprinkler releases a wide, fan-shaped sheet of water that creates a protective curtain, helping to stop flames and heat from spreading through unprotected openings.
Made from durable brass with a corrosion-resistant chrome finish, the VK795 combines strength and long-lasting protection with a clean, polished appearance. Its 3/4-inch NPT connection and 5/8-inch orifice provide a 8.1K discharge factor, offering high water flow for large or high-risk areas that require dependable, heavy water coverage.
Product Overview
The VK795 C-1 Window Sprinkler delivers a 180-degree fan-shaped spray pattern that spreads water evenly across the surface of a window or wall. This wide water curtain helps cool hot surfaces, absorb radiant energy, and prevent flames from traveling between structures. Its large orifice and high K-factor make it well suited for installations where strong, even water flow is required—such as large glass façades, process buildings, and other exposed areas.
The sprinkler operates effectively at a minimum pressure of 7 psi and can handle up to 175 psi of water pressure. Its precision-engineered deflector ensures consistent water distribution and a stable spray pattern under varying pressures. The chrome finish provides extra corrosion resistance and a professional look, making it ideal for both industrial and architectural installations.
In deluge systems, multiple VK795 sprinklers are typically installed side by side along the protected opening so their sprays overlap slightly, forming a continuous wall of water. This overlapping coverage helps maintain full protection for wide or tall window systems and prevents heat or flames from penetrating the building envelope.
Listings and Approvals
The Viking™ VK795 C-1 Window Sprinkler is UL Listed for use in fixed fire protection systems. This certification ensures that the sprinkler has been tested for safety, performance, and reliability under fire exposure conditions. While it is not FM Approved, the VK795 meets the same high standards of construction and performance found throughout Viking’s C-1 Window Sprinkler product line.
Each sprinkler is tested for consistent water flow, pressure integrity, and spray pattern accuracy. Installers and system designers should follow the manufacturer’s published data sheets and local fire protection codes to ensure proper installation and compliance.
Installation and Maintenance
The VK795 must be installed according to approved design drawings and Viking’s technical documentation. The sprinkler’s deflector should be oriented to project a smooth, even 180-degree spray across the entire protected surface. Only the manufacturer’s specified wrench should be used to install the sprinkler, and the correct torque must be applied to prevent leaks or thread damage. During installation, protect the sprinkler’s waterway from dirt and debris, and remove any temporary caps before testing the system.
Once installed, the sprinkler should be included in regular inspection and maintenance programs. Inspect the deflector and orifice to ensure they are clean and unobstructed, and verify that no objects block the spray path. If a sprinkler is corroded, damaged, or misaligned, it should be replaced immediately. Routine testing under NFPA 25 or local standards helps confirm system readiness and ensures the VK795 will perform as expected during a fire.
With its high 8.1K flow rating, corrosion-resistant chrome finish, and wide 180-degree spray pattern, the Viking™ VK795 C-1 Window Sprinkler provides reliable, high-volume protection for exposed windows and walls. It’s a strong, proven choice for deluge systems where powerful, even water distribution is critical for effective fire exposure control.
