Abrasive Metering Valves
Abrasive metering valves are at the heart of precision blasting. This category includes Schmidt®, Axxiom, and MicroValve™ units built to control abrasive flow with pinpoint accuracy. Whether you’re running a pressure-hold or blowdown system, these valves deliver reliable performance across a wide range of abrasive types, from garnet to aluminum oxide.
Choose from high-efficiency models like the Thompson Valve II XL™, compact MicroValve systems, or full retrofit kits that convert older pots into responsive, modern setups. Designed for heavy use in demanding environments, these valves help blasting contractors cut downtime and reduce media waste.

The Thompson Valve II XL™ showcases Axxiom's continuous improvement process. Adding XL™ technology to the legendary Thompson valve, this premium valve lasts up to 10 times longer than all previous Thompson valves, due to its unique engineering.- Withstands aggressive medias (like steel grit or aluminum oxide) and high-wear dusty abrasives.
- Will support up to a #12 (3/4") blast nozzle
- Upgraded components and internal wipers to keep the critical areas protected
- Most universal of the Axxiom XL™ series of valves - supports robotic, high-volume blasting
- Sold Individually
- Many choices of sizes and tungsten sleeve configurations, as follows:
- 1" base, std. sleeve. MPN: 2153-006
- 1.25" base, std. sleeve. MPN: 2153-007
- 1.5" base, std. sleeve. MPN: 2153-008
- 1.25" base, slotted sleeve. MPN: 2153-217
- 1.5" base, slotted sleeve. MPN: 2153-218
- 1.25" base, multi-port sleeve. MPN: 2153-437
- 1.5" base, multi-port sleeve. MPN: 2153-438
- (slotted and multi-port sleeves are designed to limit the maximum abrasive flow, saving abrasive when the valve is opened too far.)
-
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.
