Pinch valves

Pneumatic pinch valves consist of a hose-shaped pinch sleeve (hose collar), a housing and the connecting pieces (flange, thread, etc.). When compressed air is pressed between the housing and the pinch sleeve, the pinch sleeve is compressed and closes the pinch valve. Sealing is achieved by means of a sealing surface and not, as with most other pipe fittings, by means of a sealing line.

For this reason, pinch valves are much more contamination-tolerant than other valves and are therefore the ideal valve for solid media (bulk solids and powders), liquid, gaseous and pasty media as well as media mixtures, even if solids are present in these fluids.

KVT pinch valves are characterized by free passage, easy maintenance, simple integration into automated processes, reliability and durability.

Since 2021 we are also able to deliver AKV pinch valves and spare parts.

AKV pinch valves have proven themselves in particular for flour silo systems and as "bakery valves". They usually consist of one-piece, cast aluminum alloy housings.
