Abstract

A new pressure-only molten metal valving apparatus and method is provided. This novel approach to controlling the flow of liquids eliminates the need for active, moving valve components. Using the natural surface tension properties of liquids, the gas pressure either activates liquid flow when a threshold is overcome or retains the liquid in a head, even when lifted.
