This fire-resistant butterfly valve can be placed in ventilation ducts at wall passages to prevent fire propagation. The valve is placed in a steel ventilation duct of the same diameter and held in place by a rubber sealing ring. A melting plum keeps the two half-leaf flaps open. When the temperature in the air boiler exceeds 72 ° C, the lead melts and closes the two parts of the valve, preventing flames, smoke and hot gases. Installation, in channel, 0-360 °.
