Valve body and valve leaf: Made from galvanized steel or stainless steel, with special thickness and structure to withstand high heat.
Insulation materials: The inside of the valve body and/or leaf is lined with specialized insulation materials (such as ceramic wool, fireproof plaster) to ensure factor "I" (heat insulation).
FD EI valve is an indispensable component in fire protection systems of:
High-rise buildings: Apartments, offices, shopping centers.
Hospitals, schools: Places with large crowds and high safety requirements.
Factories and warehouses: Especially places containing flammable materials.
Data centers, server rooms: Protect sensitive equipment.
FD EI valves are often installed at strategic locations such as:
Air ducts pass through walls and floors to prevent fires.
Connection between different fire compartments.
At the duct branches from the main shaft into separate areas.
Trigger: Thermal fuse melts (for mechanical types) or thermal sensor/signal from the fire alarm system activates the motor (for motorized types).
Valve Closure: The valve leaf automatically closes completely, forming a barrier against fire and smoke.
Maintains EI: Thanks to its special construction and materials, the valve will maintain its integrity (stops fire and smoke) and insulation (keeps external surface temperatures low) for the certified time (e.g. 60 minutes, 120 minutes).
Safety of people and property: This is the most important role of the FD EI valve. It helps prevent fire and smoke from spreading, buying time for people in the building to evacuate safely and for firefighters to reach and control the fire.
Compliance with fire protection regulations: Installation of FD EI valves is a mandatory requirement according to current fire prevention regulations and standards in Vietnam and internationally.
Protecting building structures: Limiting fire damage to important building structures.
Overall fire protection system efficiency: FD EI valve acts as an important "blocking point", helping other fire protection systems (such as automatic fire suppression systems, fire alarm systems) maximize effectiveness.
