TBX Steam Conditioning Valve

Brand: Fisher
Request Information
Fisher TBX valves reduce both steam pressure and temperature to enable daily cycling of power plants.

In addition, they protect reheater tubes, condensers, and piping against excessive pressure, temperature, and enthalpy excursions during steam turbine trips.
Features
  • Combines pressure and temperature control in a single valve.
  • Rugged cage-guided design enables handling of full pressure drop of main steam.
  • Whisper Trim ™ III and WhisperFlo™ trims help to attenuate the noise by 30 to 40 dBA.
  • Use of the Fisher Bore Seal trim gives capability of standard Class V shutoff up to 593°C (1100°F). This unique balanced trim is field-proven.
  • FEA designed valve body can handle the most demanding applications without thermal stress problems.
  • Permits vertical stem orientation for ease of maintenance in most applications.
  • The cage is case-hardened for maximum life and is allowed to grow during thermally induced excursions. The plug is continuously guided and employs cobalt-based overlays for guide bands and tight metal-to-metal shutoff against the seat.
