Metering Valves

All Blast equipment requires proper metering of abrasive and that begins with a proper metering valve. There are many metering valves available from many manufactures and we can help you to choose the right one based on your application and equipment manufacture! Also, beware of aftermarket valves. While they offer a price savings, they often don’t last due to lesser quality and looser tolerances in construction.

Schmidt® MicroValve®:

The original, normally open metering valve designed to handle a wide range of abrasives. Urethane sleeve with adjustable flow capabilities. Available with an 1”, 1-1/4” or 1-1/2” NPT Base.

Schmidt® MV2®:

The next-generation valve in the MicroValve® line. Provides near-infinite, precise metering of abrasive media. This valve incorporates numerous improvements designed to increase performance, and make the valve easier to use, easier to service. Suggested for use with the ComboValve® control valve. Available with an 1-1/4” or 1-1/2” NPT base.

Schmidt® MV3®:

The Schmidt MV3 abrasive metering valve is the newest innovation in the family of industry leading Schmidt abrasive metering valves. The MV3 offers the proven productivity and safety advantages that Schmidt valves deliver to abrasive blasting operations through the precise metering of abrasive, along with an extended the service life, an improved clean out port, and easy access to wear components for safe, efficient maintenance. Available in an 1-1/4” or 1-1/2” NPT Base.

Schmidt® Thompson® Valve:

The original Thompson Valve that revolutionized abrasive metering and control. Nothing matches the performance, reliability and durability of a genuine Schmidt® valve. Shuts off abrasive flow to the nozzle and seals the tank at the same instant. Available with a number of easy to change sleeve inserts for abrasive changes and an 1”, 1-1/4” or 1-1/2” NPT base.

Schmidt® Thompson® II Valve:

The next-generation valve in the Thompson Valve line. Shuts off abrasive flow to the nozzle and seals the tank at the same instant. Ideal for multiple outlet use. Offers significant improvements over the original Thompson Valve designed to improve performance, make servicing easier and extend service life. Faster response, finer control. More sleeve choices available to accommodate a wider range of abrasives and applications. The abrasive airblast industry's choice for abrasive metering and control. 1”, 1-1/4” or 1-1/2” NPT Base choice available.

Schmidt® Thompson® II XL™ Valve:

The newest advances in abrasive metering and control valve technology are incorporated in this valve. Shuts off abrasive flow to the nozzle and seals the tank in the same instant. We designed this valve to address the unique challenges of the harshest blasting environments including those operating continuously with aluminum oxide. Nothing comes close to matching the performance, reliability, serviceability and life of this valve. If minimizing downtime and keeping your operation up and running are critical to you, you need this valve. Tungsten Carbide XL Sleeve only with 1”, 1-1/4” or 1-1/2” NPT Bases available.

Clemco® Flat Sand Valve (FSV):

An abrasive metering valve regulates the flow of abrasive from the blasting pot. Metering valves create optimum abrasive blasting efficiency by controlling the desired amount of abrasive entering the air stream. A lean air and abrasive mixture provides faster cutting, reduced abrasive consumption, increased productivity, and lower clean-up costs. The FSV Abrasive Metering Valve adjusts the flow of abrasive easily with the adjustment of the metering handle. A clean-out port allows the operator to easily dislodge abrasive clogs without removing the valve from the abrasive blasting pot. For use with expendable mineral, slag and plastic media abrasives. Normally open, 1-1/4” NPT thd only.

Clemco® Quantum Media Valve (MQV):

The Quantum Manual Abrasive Metering Valve is an easily adjustable, manually operated, abrasive metering valve which maintains precise settings from fully closed to fully open. It can be used with all common abrasives, mineral, slag or metallic. Typically sold on the contractor series line but included now as an option with the classic series. Normally open, 1-1/4” NPT thd only.

Clemco® Auto Quantum Media Valve (AQV):

The Quantum Metering Valve but with an actuator that shuts off abrasive flow to the nozzle and seals the tank at the same time. Can be used with most medias except not recommended with lightweight medias. Normally Closed, 1-1/4” NPT thd.

Clemco® Sentinel Valve (SMV):

A Normally-closed metering valve that shuts abrasive flow off to the nozzle and seals the tank. Can be used with all medias including lightweight media with a sleeve change over. 1-1/4” NPT Thd.

Other Clemco® Media valves:

  • LMV for lightweight abrasives
  • LPV for Lo-Pot machines
  • MSV- small pot metering valve
  • MPV – Manual Pinch Valve
  • PVR – Automatic Pinch Valve

Empire Sure-Flo®:

A Manually operated, normally open metering valve that delivers reliable and precise performance. Media flows thru a gum rubber pinch tube, number of options available for different media selections. 1” or 1-1/4” NPT Tee base for blast cabinet or pressure pot operations.

Empire Automatic Sure-Flo®:

An automatically operated, normally closed metering valve that delivers reliable and precise performance. Media flows thru a gum rubber pinch tube, number of options available for different media selections. The valve closes of media flow to the nozzle and seals the pot at the same time. 1” or 1-1/4” NPT Tee base for blast cabinet or pressure pot operations.

Other Manufacture Metering Valves available:

  • PK Lindsay Small, Medium or Large Mixing Valves
  • Key M-100 Grit Valve
  • Trinco 900 Series Media Manual Pinch Valve
  • Ball Valves

Blast Cabinets & Suction Machines:
