One Valve Has You Covered - You don’t need to stockpile spares or a collection of valves for different media. The GritWizard is your go-to valve for all common media types

Precision Abrasive Metering - The adjustment knob calibrated at 20 turns per inch ensures a precise media-air ratio. The numbered gauge makes it easy to return to your preferred set point.
