The abrasive metering valve is used to regulate the amount of grit going to the sandblast nozzle via the blast hose. Also known as a "grit valve", the metering valve uses pressure from the metering valve top on an internal rubber washer to regulate the flow. Tightening the hex nuts, compresses the rubber washer or donut which reduces the diameter of the opening, thus reducing the amount of abrasive going to the nozzle.

The most common repair is replacement of the Rubber Washer which is used to regulate the amount of abrasive fed to the hose. The base of the metering valve also receives a lot of abuse as the grit enters the valve vertically, directed toward the base. The second most common repair is replacement of the Metering Valve Base.
