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.


[ We claim:] [1.] A pressure regulating valve for regulating a flow of a high-temperature, high-pressure fluid comprising:a main regulating valve; anda pilot valve;wherein said pilot valve comprises:a pilot casing having a front and back end;a pilot inlet for receiving a supply of fluid;a pilot outlet for releasing a supply of fluid;a slidably mounted pilot poppet having a front end and a back end, said pilot poppet front end seated in said pilot casing front end and said pilot poppet back end seated in said pilot casing back end, wherein said pilot popp...
