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.

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.
- Sold individually.

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.

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.
