Abstract
A valve system for the finite control of abrasive media within an abrasive blasting environment. Two valves communicate in series: (i) to stop the flow of abrasive media when the deadman switch is deactivated; and (ii) to adjust the flow of abrasive media into the pressurized hose. The flow of abrasive media is controlled through a control panel housed in the blast handle at the blast site and/or through a control panel at the site of the blast generator.
