VAR Drum-Type Diverter Valves for Pneumatic Conveying
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.
Function:
VAR Diverter Valves are suitable for diverting or converting any type of powdery or granular material.
Commutation of the tubular exit and diversion of the material flow from one duct to another is obtained by a pneumatic actuator which activates the rotating inner drum.
Features
Cast aluminium alloy casing.
Various surface treatments depending on material handled.
Operating temperature: -20 °C ~ 80 °C (-4 °F ~ 176 °F).
Operating pressure: max. 3.5 bar (51 PSI.)
Closing pressure: max. 4.0 bar (58 PSI).
Activating pressure of pneumatic actuator: max. 5.0 bar (72.5 PSI).
Range includes most common pipe diameters in pneumatic conveying from 50 ~ 200 mm (2 ~ 8 in).
Benefits
Standard inflatable seals.
Lightweight and compact overall dimensions thanks to aluminium-cast design.
Minimum pressure drop thanks to special design features.
Works in both directions as diverter or converter.
VFS Butterfly Valves consist of two high-pressure aluminium alloy die-cast semi-bodies, a SINT polymer composite or cast iron swivel disc, and a pre-stressed elastomer seal.
VM/VMM-type Pinch Valves are used for interception of material flow in pneumatic conveying systems, or other pipelines. In addition, they can be installed as a locking device for silo filling pipes.
