Abstract (en)
[origin: EP2239015A1] The valve has a frame (50) and a tunnel (10) in which a butterfly damper (200) is pivotably mounted around an axis. A body (100) of the valve and the butterfly damper are produced by assemblies (211) of cut and pasted refractory plates (11, 51) i.e. sand-lime plate. The assembly forming the body and the assembly forming the butterfly damper are provided with steel reinforcements (60, 70). The reinforcements are attached onto an outer side of an assembly of the tunnel and the frame. Reinforcements (240, 250) of the butterfly damper are attached onto both sides of a blade.
