Round smoke valves are used in the installation of ventilation systems in buildings. Smoke valves stop the spread of fire and smoke through the duct system. The valve feather is made of heat-resistant material.
Round smoke valves are part of a fire protection system that prevent the spread of fire and other combustion products, such as smoke, from one fire segment to another point of construction by closing the duct. The valve blade automatically closes the duct using a closing spring or actuation mechanism. The spring is released by pressing a button or a thermal fuse. Rectangular smoke valves have two inspection openings.
The operation of the smoke valves does not depend on the direction of air circulation, they can be in an arbitrary position. Suitable for systems free of abrasive, chemical and adhesive particles. The temperature at the installation site is allowed to range from -30 ° C to + 50 ° C.
