PRESSURE SEAL GLOBE VALVE


  • Mainly used in power plants involving fossil fuels, coal, gases, nuclear and thermal power, boilers, steam stations, etc. as valves for volumetric flow control.
  • Designed to leverage the ability to use pipeline fluid pressure to enhance sealing action with a pre-loaded graphite or metal gasket strategically placed between the body and hood.
  • Designed in accordance with ASME B16.34.
  • ASME Classes 600, 900, 1500, and 2500
