Production introduction
foinbo® 2.5-inch Landing Valve is an essential fixture in fire suppression infrastructure, designed to provide controlled access to pressurized water for firefighting operations. Typically installed in stairwells, corridors, or exterior walls of buildings, this valve enables firefighters to connect hoses swiftly during emergencies, ensuring rapid response to fires.
foinbo® 2.5-inch Landing Valve is engineered for robustness, featuring a ductile iron body with an epoxy powder coating (typically 250–300 microns thick) to resist corrosion, UV exposure, and mechanical damage.
Size and Connectivity: The 2.5-inch inlet/outlet diameter accommodates standard fire hoses (e.g., 2.5" NST, BS336, or Storz couplings), enabling seamless integration with firefighting equipment.
Pressure Rating: Designed to handle working pressures up to 16 bar (232 psi) and test pressures of 30 bar (435 psi), ensuring stability during high-flow operations.
Flow Control: A quarter-turn non-rising stem or rising stem design allows precise regulation of water flow, minimizing water hammer effects.
Visibility and Accessibility: The valve is painted bright red (RAL 3000) and includes a clear direction indicator for easy identification. Some models feature illuminated signage for low-light conditions.
Anti-Tampering: A locking mechanism (e.g., breakable seal or keyed lock) prevents unauthorized use while allowing emergency access.
