The MUCON Iris Diaphragm Valve (IDV) has proved itself to be one of the most versatile flow control valves for dry bulk solids. When fitted with an elastometric diaphragm, the valve is capable of closing around lumps of products or even foreign bodies trapped during closure, whilst still providing an effective seal to smaller particles and dust. It is this unique feature that has enabled the MUCON IDV to be used for a variety of unusual valving applications. One of these applications is sealing around service tubes between clean rooms.
