Installed in the pneumatic conveying ductworks, are controlled by electropneumatic air cylinders and allow the switching of the fiber flow into two different machines. They are built in different configurations (T or Y) and models:
- Single vane – switching without material
- Double vane – switching during the material flow
- Double vane vacuum – for the feeding of two condensers in vacuum conditions
- Four way – for connecting two sources to two downstream machines in any combination with two simoultaneous flows of material.
