The sealing of removable, temporary cables, pipes and other service or process supply lines has long been a challenge facing clean room, isolation and glove box operators. Providing a gas or dust tight seal around the service lines while enabling the same lines to be easily removed when not in service or when cleaning is required has always been the major requirement.

The solution is a Mucon Iris Diaphragm Valve used to seal around both ends of the service lines as they pass through a wall or partition.

Traditionally used for the flow control of powders from hoppers and silos, the infinite variable open/close action of the diaphragm in the Iris Valve allows it to seal tight around service lines. The flexibility of the rubber or silicone diaphragm even allows a seal around multiple lines, pipes, and cables, regardless of shape, size or material of construction. (See Figure 1) Additional sealing is provided by the use of 2 diaphragms in each valve, totaling 4 diaphragms that provide a seal around the service pipes – 2 seals on each side of the wall. (See Figure 2)

When it is time to remove the service lines, the 2 valves are opened and the temporary supply lines are removed. With the use of a quick release clamp connection, the valves can be easily removed, leaving a simple plain outer pass-thru pipe in place in the wall. When not in use, the outer pass-thru pipe can be capped-off, allowing the clean room or isolator to be used without the temporary services.

The Mucon K Iris Diaphragm Valve provides the perfect solution for a temporary process supply line seal for clean rooms, isolators, and glove boxes.
