Abrasive Blasting 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.

  •  
    • Newest generation abrasive metering valve with improved wear-life while maintaining fine metering control.
    • Offers improved life and lower cost over previous generation Thompson valves.
    • Pressure-hold design maintains pressure in the pot, even with deadman released.  This can save up to 15% of abrasive when your projects involve a lot of start-stop blasting.
    • Diaphragm-activated piston requires minimum of 75 psi control pressure
    • Can be retrofitted to a blast pot with only 6" clearance
    • Genuine Parts - Manufactured by Schmidt® / Axxiom Manufacturing

  • When Axxiom released the Thompson 2 valve, the benefits of Pressure-Hold technology were instantly upgraded by improved user experience over the Thompson I valve.  Details as follows:

    • Improved servicability:
      • Body and cylinder are now 2 parts, providing easier removal of sleeve and plunger.
    • Additional Seal protection:
      • Has 3 separate seals (versus the original 1), reducing dust migration and improving durability.
    • Multiple Sleeve choices:
      • In addition to the original Tungsten Carbide and Urethane full-flow options, Axxiom has released additional options that help prevent over-consumption in various applications.
    • Virtual Position Indicator:
      • Simplifies setting of the media flow rate.
    • Cleanout:
      • Full 1" port directly under the inlet allows cleanout without removing the valve.
    • Size info:
      • Standard 1-¼” (32 mm) inlet thread
      • 4 choices of MNPT piping for pusher-line connection
        • 1", 1-¼", 1-½", and 2"
    • Options:  Make servicing the valve even more convenient with one of the following:

    Meter your abrasive efficiently and conveniently with the genuine Axxiom Thompson II valve!

  • The Thompson I Valve was invented by Bob Schmidt and was instrumental in causing the popularity of pressure hold technology.

    • Pressure-hold systems retain the pressure in the blast pot until the deadman handle is depressed.  This reduces abrasive and energy waste.
    • The Thompson I offers fine control for abrasive metering
    • It comes in 3 nipple size configurations:
      • 1 ¼” (32 mm) x 1 ¼” (32 mm)
      • 1 ½" (38 mm) x 1 ½" (38 mm)
      • 2" (50 mm) x 2" (50 mm)
    • Threaded-plunger metering design with air actuated operation
    • Fits most sand blast hoppers, blast pots or abrasive blasting machines
    • Genuine Parts - Manufactured by Schmidt® / Axxiom Manufacturing

    Note:  The Thompson I valve, while still available, has become less common. The more modern Thompson II valve or state-of-the-art TeraValve are more popular and can replace the Thompson I without any modifications.

  • The Flat Sand Valve is legacy metering technology, where the metering is performed by sliding a lever to open and close the abrasive port.  It is simple in design and relatively inexpensive, but has a few limitations.  Details as follows:

    • Slide-plate metering design, controlled by lever
    • 1 1/4" (32 mm) ports
    • Features side cleanout-inspection port
    • Available with or without outlet nipple and Y-piece (Optional rubber lined nipple is available to extend nipple life.)
    • The major limitations are:
      • Not recommended for use with metallic abrasives
      • The slide plate/lever design does not provide effective fine metering control.  Typically this results in over consumption of media.  For low-volume blasting using inexpensive media, this may not be an issue.

    Note:  These limitations can be eliminated by replacing the FSV with a MicroValve 3.  No modifications required.  Alternatively, legacy pots with inlet-outlet controls and FSV technology can be completely modernized with either the MicroValve Retrofit Kit (for pressure-release technology) or the TeraValve Retrofit Kit (for pressure-hold technology).
