Overview
The Viking™ VK795 C-1 Window Sprinkler (Part Number 01325BA) is a high-capacity, open-type sprinkler designed for use in deluge fire protection systems. It provides dependable protection for windows, walls, and roofs that are exposed to flames, radiant heat, or fire from nearby structures and equipment. When activated, the sprinkler discharges a wide, fan-shaped sheet of water that forms a continuous curtain, helping to block heat and slow the spread of fire through glass or open building areas.
Built from corrosion-resistant brass, the VK795 offers strength and long-term reliability for demanding fire protection environments. It connects using a 3/4-inch NPT thread and features a large 5/8-inch orifice with a 8.1K discharge factor. This high K-factor design delivers powerful water flow and extended coverage, making it suitable for protecting large windows, wide openings, or structures that face high heat exposure risks.
Product Overview
The VK795 C-1 Window Sprinkler produces a 180-degree fan-shaped spray pattern that spreads water evenly across a window or wall surface. The flowing sheet of water helps cool the surface and blocks flames or radiant heat from passing through. This makes the sprinkler ideal for use in deluge systems where fast, high-volume water discharge is needed to protect building exteriors and structural openings during a fire.
The VK795 operates effectively at pressures as low as 7 psi and can withstand up to 175 psi of rated water pressure. Its precision-machined deflector ensures a stable, even spray pattern that maintains full coverage across a wide area. In most systems, several sprinklers are installed in a row, positioned so their sprays overlap to form a seamless wall of water for full exposure protection.
Designed for performance and durability, the VK795 is used in a variety of applications, including manufacturing plants, warehouses, chemical facilities, and exterior walls or façades where radiant heat exposure is a concern. Its high flow rate and rugged construction make it a trusted option for engineers and fire protection professionals needing strong, reliable water delivery.
Listings and Approvals
The Viking™ VK795 C-1 Window Sprinkler is UL Listed for use in fixed fire protection systems. This listing confirms that the sprinkler meets recognized standards for safety, performance, and reliability. While not FM Approved, it offers the same robust construction and proven performance found throughout Viking’s C-1 Window Sprinkler line. Each unit is factory-tested to ensure consistent operation, accurate spray distribution, and pressure durability.
Installers and designers must follow Viking’s published technical data sheets and applicable fire protection standards to ensure proper system performance and compliance with local codes.
Installation and Maintenance
The VK795 must be installed exactly as shown in the approved system drawings. The deflector should face the surface being protected, creating a smooth, even 180-degree fan of water across the window or wall. Use only the manufacturer’s specified wrench and apply the proper torque to prevent leaks or damage. During installation, keep the waterway free of dirt or debris, and remove any protective covers before testing.
Regular inspection and maintenance are important to ensure reliable performance. The sprinkler should be checked for corrosion, mechanical damage, or blockage and confirmed to be securely mounted and correctly aligned. Any sprinkler that is blocked, bent, or corroded should be replaced immediately. Periodic system testing, as required by NFPA 25 or local codes, ensures that the deluge system operates correctly and that the spray pattern remains unobstructed.
With its solid brass body, large 8.1K discharge factor, and wide 180-degree fan spray, the Viking™ VK795 C-1 Window Sprinkler provides powerful and reliable protection for exposed windows and walls. It’s a proven choice for facilities that need strong, consistent water coverage in demanding fire protection applications.
