So-called "smooth" design is dedicated for conference rooms, office spaces, residential buildings, etc.


Principle of valve functionality


The valve is secured on the top of the door filling with a special cord, which, in the case of a fire, is released as a result of heat (90 - 95°C). The valve drops into the lower part of the frame by its own weight, where it is sealed with a foaming band around the circumference and sides.
