Abrasive Metering Valves & Parts

The heart of any blast pot is the abrasive metering valve, which acts as the regulator to feed the blasting abrasive into the high pressure & high velocity compressed air stream. Regardless of the media type, money can be saved if your metering valve has fine-adjustment control. Too much abrasive will flood the airstream – this can actually slow down the blasting operation – as well as waste media. Too little abrasive will starve the compressed air stream, and slow production as well. Setting the abrasive metering valve precisely is imperative for high production abrasive blasting operations. BlastOne has represented the Schmidt by Axxiom Manufacturing line of metering valves for decades.  Schmidt valves became the benchmark when they released the Thompson valve years ago, and have continued their tradition of innovation with the TeraValve and MicroValve III.  These valves come in a variety of configurations and all set the standard for precision abrasive metering.
