The 100DR-3750 is a severe service, multi-stage control valve designed specifically for boiler feed pump recirculation in supercritical and ultra-supercritical power plants. In these advanced power plants, recirculation valves may experience operating pressure differentials exceeding 350 bar (5000 psi) and design pressure requirements up to 480 barG (7000 psiG).

The 100DR-3750 is engineered to provide precise, reliable control while in service and ensures tight shutoff when closed. The valve internals (trim, plug assembly, and seals) are designed to withstand extreme pressure differentials.
