Abstract
A metering valve for delivering liquids from a reservoir includes a rotatable valve plug having at least one well in the valve plug. The valve plug prevents direct communication across the valve. Rotating the valve plug transfers the liquid from the reservoir into the well on the valve plug. Rotating the valve plug further transfers the liquid in the well from the valve plug to the point of delivery. The rotation of the valve plug can be repeated to transfer more liquid. The metering valve can be used to deliver vaporizable germicides to a sterilization chamber. A single metering valve can be used to deliver varying amounts of vaporizable germicide to different sizes of sterilization chamber by rotating the valve plug an appropriate number of times. The valve plug can contain multiple wells to deliver large volumes of liquid quickly.
