Fire damper cartridge SC 60'-90'-120'


Round butterfly valve has a fire resistance of up to 120 minutes. They are equipped with a thermal fuse that keeps both parts of the blade open. Once the temperature in the jacket is higher than 72°, the thermal fuse is activated and the two blades close. The valve is then in the closed position. Two stop tabs lock the blades in this position and ensure a perfect seal of flames and smoke. The connection valve is placed in a metal ventilation duct of the same diameter and is held in place by the rubber gasket.

Round butterfly valves are a compact fire-resistant solution for small diameter ducts. Installed at wall passages to stop the spread of fire, they are distinguished by their simplicity of installation.
