• Steel Grit (Metering) Valve is used to provide metering of abrasive into the compressed air flow at the outlet of a blast machine. • Steel Grit (Metering) Valve is suitable for metering heavy or aggressive abrasive materials, such as steel shot and grit, chilled iron grit or aluminium oxide. • Steel Grit (Metering) Valve design prevents the valve body from coming into contact with the abrasive stream. The abrasive stream only touches the rubber liner, which may be quickly replaced when worn. • The abrasive is metered by means of closing the rubber pipe by a adjustment screw.
