1.1 This specification covers self-contained, internally operated, globe style, pressure-reducing valves for use in steam service. In these valves, the downstream pressure feedback is sensed by a spring-loaded diaphragm to position a pilot valve-the pilot valve uses the inlet steam pressure to position the main valve plug by means of an operating piston.
