  • Ball valves for throttling BFW (high erosion at partial open)
  • Cast iron valves for high-pressure BFW

Service Considerations

  • IBR certification mandatory for all valves on Indian boiler feedwater and steam systems
  • Stellite-faced seats and discs essential on globe and check valves to resist erosion
  • Pressure-seal bonnet gate valves required above Class 900 for high-pressure BFW
