Faster switching and a higher number of switching cycles enable more efficient production and higher productivity through increased output. The long service life of the PTFE bellows reduces production downtime.
The best quality of your products throughout the entire production process is important to you.

The long service life of the PTFE bellows, optionally also available with a stainless steel or PEEK cap for liquids with granules, guarantees short downtimes.
Due to open folds, even when open, the cleaning behavior is optimal.
Several valves, combined to form valve blocks in filling machines, fill products such as yoghurt aseptically and perfectly.
Suitable valve for filling application available:
Some products, e.g. yoghurt in a cup or baby food in a jar, are filled into the container from above (via a mirror). Others are filled through a lance just above or even below the mirror, e.g. salad dressing or shampoo.
On request.
All valves are available in special materials such as Hastelloy® C-22, 1.4539/904L, 1.4529, AL-6XN® and others .
