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.

Have a good pot that you hate to throw away? The TeraValve™ Complete Blast Pot Retrofit Kit allows you to obtain state-of-the-art pressure-hold abrasive metering technology and save money in the process! Details as follows:
- Your existing pot must be structurally sound and must have at least 6 inches clearance below it.
- The retrofit kit includes a new TeraValve™ as well as all other valves, piping, deadman handle/controls, and hoses required for a complete upgrade.
- Note: Handway and pop-up components are available separately, if needed. In addition, you may want to consider the optional VBS II muffler and/or a union-end ball valve / quick connect (if you have the necessary clearance). See Related Products below.
- Retrofit kits are available in either pneumatic or electric and are offered in both 1-¼" and 1-½" valve sizes.
- Installation instructions are included in the box (and under the Documents tab here). If installation assistance is needed, call us for friendly tech support via phone or we can arrange to have our technicians perform the installation for you.

- 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:
- Union-End Ball Valve - The UEBV allows removal of valve without emptying the pot.
- Tri-Clover Quick Connect - allows removal of valve without tools.
- Combination UEBV and Tri-Clover - combines the benefits of both options at a reduced cost.
- Improved servicability:
-
- Pressure-release deadman control valve i.e., blast machine depressurizes when the deadman handle is released.
- Used when an overhead hopper automatically feeds abrasive into a blast machine.
- Rugged stainless steel body, compact, isolated 2-bolt construction.
- Doubles blast machine refill cycle time.
- Virtual Position Indicator illustrates orifice size, giving the ability to set abrasive flow quickly and consistently.
- Set and forget – flow rates stay set where you put them.
- High wear, rugged plunger seal.
- Stainless steel body for long life.
- Improved urethane clean-out port enabling quick removal of obstructions while improving port and valve life.
- Fit a rebuild kit while the valve is still fitted to the blast machine.

Schmidt changed the abrasive blasting industry when they introduced the MicroValve™. Now known as the MicroValve I (or the Original Microvalve), it is still available although most pressure-release Schmidt pots now use the newer MicroValve III®. It features:
- Simple threaded screw-type metering
- Hardened steel threaded base nipple
- (The brass threaded coupling shown is available separately.)
- Genuine Products - Manufactured by Schmidt® / Axxiom Manufacturing
-
- Thompson Metering Valve II lasts up to 10 times longer than any other valve, due to its unique engineering
- Designed to handle the harshest blasting environments known
- Will handle up to a 3/4" blast nozzle
- Will work with any abrasive, including very fine/dusty abrasives
- Most rugged and reliable valve for any application
- Sold Individually
- Genuine Parts - Made in USA by Schmidt / Axxiom Manufacturing

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

GV02427
- The Flat Sand Valve is the classic Clemco abrasive metering valve used for sandblasting for nearly 100 years.
- 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).
- The valve uses a simple lever and keyslot to control the flow of abrasive from the blast pot into the blast hose
- 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.
- Genuine Clemco Part Number 02427

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.
