🔍 Key Concepts

• Steam pressure reducing valve flow path from inlet to outlet • How downstream (reduced) pressure is communicated back to the control section • Difference between a pilot line feeding actuating steam and a sense line feeding pressure to a diaphragm or piston

💭 Think About

• Trace where the steam at the OUTLET side would need to go so that the valve can "feel" the reduced pressure and adjust itself—does item C connect the outlet region to a control element? • Look closely at what component is directly influenced by the pressure carried through C: does it act on the main power piston, the pilot valve, or the diaphragm/spring assembly? • Ask yourself which item in the drawing would actually move in response to downstream pressure changes, and which small passages must supply that pressure.

✅ Before You Answer

• Verify whether C connects the outlet (low‑pressure) side to a chamber above or below any diaphragm or piston. • Check if C appears to be a balanced passage around a valve element (suggesting equalization above and below), or a single feed line going to a sensing/control space. • Confirm whether there is a separate line that obviously supplies high‑pressure (inlet) steam to the pilot and power piston; contrast that with C’s location and connections.
