Flat Sand Valve
The included manually-operated Flat Sand Valve (FSV) can be used with expandable mineral and slag abrasives, as well as plastic media. However, the FSV does not work well with metallic media.
Note: This is just the machine itself with Flat Sand Valve. If you are purchasing a blast pot separate from accessories and materials necessary for blasting, keep in mind the compatibility of parts and the machine.
