| Suppose the illustrated self-contained, internal-pilot, piston-operated steam pressure- reducing valve is part of a 600-to150 psig reducing station. If there was an increase in demand for steam downstream, what statement correctly represents how the valve would initially respond? GS-0044 |
| A) The downstream pressure would drop, causing the control diaphragm to flex upward and further close the pilot valve. |
| B) The downstream pressure would drop, causing the control diaphragm to flex downward and further open the pilot valve. |
| C) The downstream pressure would rise, causing the control diaphragm to flex upward and further close the pilot valve. |
| D) The downstream pressure would rise, causing the control diaphragm to flex downward and further open the pilot valve. |
