Abrasive Metering Valves

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.

  • OEM Clemco Flat Sand Valve (FSV)
    GV02427

    The FSV is the classic Clemco metering valve.  Used in most new Classic blast machine pots, the FSV is simple and economical and provides abrasive metering control for expendable mineral abrasives and slags (not recommended for steel grit or aluminum oxide).  It is good practice to keep a complete spare valve on hand to use when needed, repairing the worn valve at a convenient later time.

  • Schmidt® TeraValve™ XL

    The industry-proven Schmidt TeraValve™ XL metering valve is revolutionary in its ability to provide high performance abrasive metering while boasting an enhanced service life.

    • Durable.  The XL (extended life) technology offers more durability - even when blasting with aggressive media like aluminum oxide or steel grit.
    • Convenient.  No special modifications are required to swap an older pressure-hold valve (like the Thompson) to a Tera. Even older pressure-release pots can be upgraded with a TeraValve Retrofit Kit, as long as there is at least 6" clearance from the bottom of the pot.
    • Preferred.  BlastOne provides the Tera Valve as standard equipment on all new blast equipment.  In addition, we use them in our own rental fleet.
