Suitable for liquid, fibrous and particulate products such as yogurt, soups with meat deposits, strawberry jam.
A more efficient production and higher productivity by higher output is possible by faster switching and higher switching cycles. The durability of the PTFE bellows reduces production losses by reduced downtime.Best quality of your products in the entire production process is the utmost importance for you.

The long service life of the PTFE bellows, optionally available with stainless steel cap or PEEK cap for liquids with grains, ensures low downtime.
Because of open folds in the open state, the cleaning performance is optimal.
Several valves, combined to valve blocks in filling machines, aseptically fill up products like yogurt.
On request.
All Valves are available in special alloys, such as Hastelloy® C-22, 1.4539/904L, 1.4529, AL-6XN® and others.
