摘要： A novel metering valve is used to split the streams in which a continuous fluid stream passes unregulated through the valve along a primary flow path. A second stream is formed by passing a small portion of the fluid in the primary flow path through a passage in a valve seat. The fluid passing through the valve seat is precisely metered by a valve stem which engages the valve seat passage to control the amount of fluid diverted from the primary flow path. Both fluid from the unregulated primary flow path and through the metered flow path flow simultaneously from the valve. The metering valve of the invention has particular use in processes for dividing a condensed distillate stream into a product stream and a reflux stream.
