Valve

☆Fire dampers act as the first line of defence during accidental fires, preventing the fire from spreading by cutting down the air supply. This device saves crucial time during an emergency by nipping the problem in its bud.

☆A fire damper maintains the integrity of the fire, separating elements by automatically closing the passage for a specific period, which prevents the fire from spreading to other parts of the building.

☆Even if there is no one in the building, the fire dampers work with absolute precision by shutting down the valves of the HVAC system and not allowing the fire to spread. In addition, they automatically close off air ducts and ventilation openings when they detect high temperatures, smoke, or flames.

☆The damper consists of a metal frame with a blade or shutter that can be horizontal or vertical and is held in the open position by a fusible link or thermal sensor. When the temperature in the duct or ventilation opening reaches a certain threshold, the link or sensor activates, causing the blade or shutter to close and block the passage of air and smoke.
