Abstract
A pneumatic regulating valve that operates on high-temperature, high-pressure gases. This invention reduces the upstream pressure of a flow of gas, which can be as high as 10,000 psia, down to a level usable by downstream control valves, which may require controlled pressure input. The springs and seals of this invention are isolated from the high temperature and pressure of the upstream gas, thus enabling regulation of gas flows of up to 10,000 psia and 2,500.degree. F.
