Clean valve guide in ice cream filling plant

In the valve, which is used to fill ice cream with fruit pieces, O-rings were used to support and guide the piston, which quickly wore out and led to piston jamming. The developers were therefore looking for an alternative that was as lubrication-free and maintenance-free as it was durable.

The solution was found at igus®. The O-rings were replaced with a new special seal and iglidur® plain bearings, which serve as a support and guide ring for the piston. Free of external lubricants, the bushings are suitable for the food sector and easy to replace. Wear has been reduced to a minimum and there are no more piston jams.
