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, while 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.
The problem: the transfer of material from one ‘condition’ to another, such as between light and dark rooms or rooms with a pressure differential.
Should cleanrooms operate at a slight over pressure, with one being at a higher pressure than the other, problems or pressure loss can occur on a regular basis.
The need: Operators require an effective, hygienic and reliable way of sealing around the tubes passing ‘through the wall’, separating one condition from another, such as temporary sealing of service pipework or tubing, e.g. CIP, gas pipes etc.
The solution: The MUCON high hygiene K-Series Iris Diaphragm Valve with quick-disconnect flanges brings the tubes together and closes tightly around them.
The material flows freely without pressure leakage or damage to the tubes. The one-piece moulded diaphragm also acts as the valve gasket. In addition, both the diaphragm and the valve itself can easily be removed without tools.
