Operating Principle; Permitted Use; Improper Use Not Permitted - WAMGROUP TOREX VM Series Assembly And Main Instructions For Use And Maintenance

3.3 Operating principle

Under normal operation conditions there is no compressed air inside the valve body; allowing, thus, the flowing
of the material inside the valve.
In the case of "stimulated" operation, compressed air is present inside the valve body and exerts pressure on
the sleeve, allowing the closing of the valve and, as a consequence, prevents the flowing of the material.
