Internal Fire Hydrant Landing Valve (Flanged/Threaded, 2.5") An industrial-grade, high-pressure internal fire hydrant landing valve engineered to provide a dedicated water outlet for fire brigade hose reels inside commercial buildings. Featuring a heavy-duty cast bronze or brass body, an oblique-angled outlet layout for seamless hose deployment, and compliance with rigorous international safety standards (such as BS 5041 Part 1), this manual globe valve delivers dependable, leak-proof control under extreme hydraulic pressure configurations.
High-Pressure Water Access Points for First-Responder Riser Lines
Within multi-story commercial offices, hotel towers, and massive industrial complexes, structural fires must be tackled directly from internal staging zones. Landing valves, also universally known as Internal Hydrants, serve as the vital mechanical connection points installed along dry or wet riser pipes inside building stairwells. They provide emergency firefighting teams with immediate access to the building's pressurized water reserves.
Our landing valves feature a space-saving Oblique-Pattern (angled) configuration, reducing space constraints inside narrow emergency exit corridors and preventing the connected fire hose from kinking at sharp angles. Fabricated from high-tensile, corrosion-resistant copper alloys, the valves are engineered to withstand continuous exposure to stagnant, treated riser water without scaling or freezing. The internal valve mechanism utilizes a renewable rubber disc that forms a bubble-tight seal under high static pressure, yet spins open smoothly using a low-friction handwheel to deliver high-velocity streams during emergency operations.
Key Performance Features
Premium Corrosion-Resistant Construction: Cast from high-quality bronze (LG2/Leaded Gunmetal) or heavy brass, shielding the valve assembly from internal mineral scale buildup and atmospheric oxidation.
Ergonomic Oblique Geometry: Engineered with an optimal down-angled outlet, simplifying the process of rolling out heavy fabric fire hoses under pressure while minimizing structural space requirements inside fire cabinets.
Instant Quick-Connect Outlet Coupling: Outfitted with a standard $2.5"\text{ (65 mm)}$ female instantaneous outlet coupling featuring internal spring-loaded catches for instantaneous, tool-free fire hose deployment.
Secured Blank Cap & Retention Chain: Equipped with a rugged brass or plastic blank plug held securely by a brass link chain, sealing the outlet against dust accumulation, debris, and unauthorized tampering when idle.
Strict Hydrostatic Pressure Validation: Fully engineered and tested to hold tight under intense hydrostatic pressure metrics, withstanding body test pressures up to 22.5 to 30 bar to prevent catastrophic failure under intense fire pump churn.
Vandal-Resistant Handwheel Lock Options: Features an integrated leather strap and padlocked pin assembly option, allowing building managers to secure the handwheel against vandalism while ensuring rapid cutting-release access for emergency crews.
Ideal Infrastructure Applications
High-Rise Emergency Stairwells: Strategic wall-mount deployment inside protected concrete exit enclosures, connecting directly to the main vertical wet riser pipes on every floor.
Industrial Fulfillment Warehouses: Installed alongside internal pedestrian structural pillars to supply heavy-duty hose deployment points across wide logistics floors.
Commercial Parking Structures: Providing rugged, freeze-resistant water access checkpoints across multi-tier open concrete parking decks.
