Pinch valves are designed for limiting or preventing the flow of materials in pipelines. Their main feature is that there are no mechanical parts that could obstruct the material flow when the valve is in open position.

OZB pinch valves are used during pneumatic transfer of powder or granules and they are widely utilized in food, chemicals, water treatment, cement and similar powder related industries.


The working principle of OZB pinch valves is; closing of the elastomer sleeve by blowing air between the sleeve and housing so that the powder flow is guided by the opening of the sleeve.
