Control Valves for Power Plant Application Nuclear, Fossil

Unlike the boiler feed pump recirculation valve, the feedwater start-up valve generally does not need the same amount of cavitation protection at all valve travels since pressure drop changes with travel. Therefore, a X[iks]-trim characterized cage may be used. The normal recommendation is a small HA design with X[iks]-trim (18 turns)

Severe service valves Boiler Feedpump Recirculation Valve

Therefore, the boiler feedpump recirculation valve will be in the closed position for 90% to 95% of the time in most power plants. This valve will also have the highest differential pressure across the seat of any other valve in the plant. This makes the recirculation valve one of the most severe duty valves in a generating plant.
