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. Because of this, replacement of the Metering Valve Base is the second most common repair. SAFE metering valves are the heaviest with the thickest cast iron base, where it counts. Lower quality Metering Valves typically have thinner bases which wear out more quickly, increasing downtime and repair costs. Because of this, SAFE metering valves save money.
