  • METERING VALVE FOR ABRASIVE MEDIA
    Publication number: 20250319573
    Abstract: A metering valve for introducing media into a pressurized fluid includes media passaging having a media inlet for receiving media and a media outlet for dispensing media toward the pressurized fluid. The media passaging defines a flow path extending from the media inlet to the media outlet and is configured to permit flow of media along the flow path. A plunger, including a plunger head, is movable between a closed position in which the plunger head forms a seal to prevent flow of media through the media passaging and an open position in which the plunger head permits flow of media through the media passaging. The seal formed by the plunger head includes a first sealing interface and a second sealing interface downstream along the flow path of the first sealing interface.
