Butterfly Gates for Pneumatic Conveying Systems

The Butterfly Gate controls gravity flow discharge from storage bins or hoppers.

Butterfly Gates are well suited for controlling air-only lines in pneumatic conveying systems. Multiple gates can be used in a vacuum system to select the destination receiver.
