Brochure Control Valves for Power - Emerson Electric

Boiler Feedpump Recirculation Valve The boiler feedpump recirculation valve faces some of the toughest conditions of any control valve in a power plant. The boiler feedpump takes its suction from the deaerator at relatively low pressure, and increases the pressure to approxi-mately 10 percent above the main steam pres-sure.

Severe Duty (SD) Control Valves - Crane Engineering

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.

Recirculation control valve replacement cuts maintenance

Oct 09, 2019 · Responsive and repeatable control of the Boiler Feedwater Recirculation (BFR) Valve protects a plant's investment in the boiler feedpump while allowing it to deliver the required flow to the boiler. The feedwater recirculation valve is responsible for taking almost a full pressure drop across the valve. This valve is typically designed for Class V shutoff and to fail-open on loss of power since it is …

The start-up valve will have much the same service conditions as the boiler feed pump recirculation valve. That is, high inlet pressure and full drop. This valve needs anti-cavitation trim and tight shut-off. Unlike the boiler feed pump recirculation valve, the feedwater start-up valve generally does not need the same amount of cavitation
