PowderFlow Butterfly Valve
The Young Industries PowderFlow Butterfly Valve is specifically designed for use in dry powder handling applications. The patented valve utilizes a specialized disc lined with TransFlow® fluidization media. The TransFlow® disc fluidizes and conditions even the most cohesive powders.
Features & Options
We've combined durable, robust construction with innovative TransFlow® technology to deliver unmatched flow control and reliability. The lowest point of the hopper, where the valve attaches to its discharge connection, is the most effective area to begin fluidizing and conditioning powders for repeatable flow.
With the PowderFlow Butterfly Valve, the process starts inside the valve itself where TransFlow® fluidization media and the TransFlow® disc fluidizes and conditions the powder so that it flows smoothly and easily.
