Blastmaster Maxum I 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 Blastmaster® Maxum I Abrasive Metering Valve is an air-actuated, normally-closed metering valve for use with a pressure-hold remote control system. When the remote control system is activated, an air signal is sent to the Blastmaster® Maxum I Abrasive Metering Valve, opening the valve, allowing abrasive to flow from the abrasive blasting pot. When deactivated, the Blastmaster® Maxum I Abrasive Metering Valve returns to the closed position, deactivating the flow of abrasive exiting the abrasive blasting pot. Typical applications include blast rooms, blast yards, bridges, oil refineries, pipelines, and storage tanks. Common abrasives used include aluminum oxide, garnet, glass bead, mineral abrasives, slags, staurolite, and steel grit/shot.

INCREASED PRODUCTION

The Blastmaster® Maxum I Abrasive Metering Valve is most often used with pressure-hold remote control systems, where the abrasive blasting pot remains pressurized. By deactivating the flow of abrasive ahead of the mixing chamber, the Blastmaster® Maxum I Abrasive Metering Valve prevents abrasive from filling up the abrasive blasting hose, greatly reducing “abrasive chugging” at activation.

PRECISION METERING

The Blastmaster® Maxum I Abrasive Metering Valve screw-type design delivers superior metering, providing a precise air and abrasive mixture for maximizing production.
