Clemco Part # 02427, Flat Sand Valve (FSV) is a manually-operated media valve that comes standard on classic blast machines ranging from 2 cuft to 20 cuft. It can be used with expendable mineral and slag abrasives, as well as plastic media. However, the FSV does not work well with metallic media. This manually-operated abrasive metering valve has a 1-1/2" NPT connection to the pot.
