valves for vacuum control




INVA 52 is a 5-way, 2-position reverse airflow vacuum valve


Rapid vacuum interception and interruption


The main application is using each of the 2 stable states to achieve a suction function or a repulsion function alternately.

This is why the INVA 52 vacuum valve is the ideal solution in automation applications such as:

- Quick gripping and release function in automatic handling operations

- Pneumatic conveying in automatic handling operations

- Rapid gripping and release functions in automatic loaders

- Vacuum gripping tables

- Packaging systems
