Flex Tube Diverter

The unique design of the Vortex® Flex Tube Diverter™ eliminates material cross contamination through a positive seal across the closed port. Pockets where material can lodge and remain trapped have also been eliminated.

• Can be shifted on a flowing column of materials – also known as, “shifting on the fly.”
• No material cross-contamination into the opposite line(s)
• Live loaded, wear compensating hard polymer pressure plate seals
• Positive seal of materials/dust-tight seal across the closed line(s) and to the atmosphere
• Machined, full-bore orifice for unobstructed material flow and to maintain convey line pressure
• The “scissoring” action reduces seal wear and minimizes material shearing
• No internal cavities, to prevent wedging, lodging and spoilage
• No pinch points or exposed moving parts
• Mechanically self-cleans its seals with each actuation
