VAR Diverter Valves are suitable for handling any type of powdery or granular material in pneumatic conveying systems.  By means of the pneumatic actuator, which activates the rotating inner drum, the commutation of the tubular exit and, consequently, deviation of the material flow from one duct to another is obtained.  VAR Diverter Valves consist of a cast aluminium casing and cover, an inlet and two outlets. The rotating internal drum optionally closes one of two outlets which are connected with pneumatic conveying ducts.  Rotation of the internal drum is activated by a pneumatic actuator.  Perfect sealing is guaranteed by internal, pneumatically inflatable seals.
