K-Series Abrasive Metering Valve
An abrasive metering valve regulates the flow of abrasive from an abrasive blasting pot. Metering valves create optimum abrasive blasting efficiency by controlling the desired amount of abrasive entering the air stream. A lean air and abrasive mixture provides faster cutting, reduced abrasive consumption, increased productivity, and lower clean-up costs. The K-Series Abrasive Metering Valve offers a simple design that is easy to operate and maintain. With only three primary wear parts, the K-Series is simple to repair. The durability of the cast iron body minimizes downtime. Typical applications include blast yards, bridges, shipyards, and storage tanks. Common abrasives used include crushed glass, mineral abrasives, slags, and steel grit/shot.


The K-Series Abrasive Metering Valve allows the operator to set and maintain a high volume flow of abrasive, allowing for increased production rates at the nozzle.


The K-Series Abrasive Metering Valve does not have any internal moving parts, meaning less time troubleshooting and increased production.


Our commitment to producing the highest quality products in the industry demands strict control over our raw materials and manufacturing processes. All components used in the manufacturing of Marco products adhere to strict process controls as specified by Marco’s Quality and Engineering team.
