Abstract:
1. A metering valve for controlling a flow of a molten metal between a first molten metal containing component and a second molten metal containing component, the metering valve comprising: a first and second vertical sealing plates disposed between the first molten metal containing component and the second molten metal containing component to block the flow of the molten metal between the first and the second molten metal containing components, the first and second sealing plates spaced apart from each other to form a valve chamber between the first and second sealing plates, the valve chamber located external to the first and second molten metal containing components; a sealing port disposed in each of the first and second sealing plates to allow the flow of the molten metal between the first and the second molten metal containing components through the sealing port in each of the first and second sealing plates; and a sealing means comprising a sealing element at a first end of a sealing tube for each of the first and second sealing plates, the sealing means selectively inserted in the sealing port in each of the first and second sealing plates to prevent the flow of the molten metal between the first and the second molten metal containing components.
