A portable dust collection supplier was commissioned to design a portable blasting recycle system of the back of a trailer. The company had already mounted a dust collector on the trailer, but needed a flow control valve to allow the blasting grit to leave the system. The grit that is produced is very fine, abrasive, and free flowing. After visiting our booth at a tradeshow in Houston last year, the company remembered our Vacu-Valve we had on display and contacted Aerodyne to see if it would work with this blasting grit, and act as a flow control valve.

The open-construction Platypus and the closed-construction Armadillo trickle valves are the most economical ways to manage dust discharged from bag filters or cyclones under negative pressure. The fitted duckbill sleeve adjusts to the desired vacuum and material is continuously discharged. It requires no controls, lubrication or power supply and easily handles abrasive materials. This trickle valve can be used in higher temperature applications as well. The Vacu-Valve® dust discharge trickle valve is available at a fraction of the cost of the rotary airlock valves it replaces. Additionally, there are multiple duck bill sleeve options available to better suit a wide variety of applications.

The Vacu-Valve was a perfect fit for this mobile blasting recycle system. Fixed to the dust collector, it was able to control the grit powder perfectly as it left the system.
