Functional description
In the event of a fire, fire protection valves shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments.
In the event of a fire, the valve is triggered at 72 °C by a fusible link. The release mechanism is accessible and can be tested from the outside.
Volume flow rate at differential pressure Δpst < 35 Pa (supply air)
Volume flow rate at differential pressure Δpst < 35 Pa (extract air)
Fire protection valve for the isolation of duct penetrations between fire compartments. For use in supply air and extract air systems; with two-stage adjustment device for adjusting the air volume.
Ready-for-operation unit, which includes a fire-resistant valve cone and a release mechanism.
Tested for fire resistance properties to EN 1366-2, with CE marking and declaration of performance according to the Construction Products Regulation.
For mortar-based installation into solid walls and ceiling slabs, and into lightweight partition walls with metal support structure and cladding on both sides.
Casing length 150 mm (300 mm with extension piece)
For the connection to ducts made of non-combustible or combustible materials.
Thermal release at 72 °C.
