Abstract
A media control valve used to meter and dispense an amount of abrasive media from a supply pot to a compressed air line for blast cleaning comprises a vertical media passage communicating with the supply pot and an air flow tube and a restricting orifice in the media passage to meter the amount of abrasive media flowing therethrough the vertical passage into the air flow tube, the media passage downstream of the orifice converging into a slot-shaped outlet into the air flow tube wherein the length of the outlet is directed along the direction of air flow through the air flow tube so as to reduce the perimeter of the outlet placed perpendicular to air flow and consequently reduce turbulence as the air passes across the outlet. The media valve is particularly useful in metering and dispensing sodium bicarbonate media from a supply pot to the air conveying line by means of differential pressure across the orifice.
