The VBSE is a steam conditioning valve used for steam throttling and desuperheating through spray water injection, directly at the outlet. Used for start-ups and load rejection, they bypass the steam to various reheat lines until the steam temperature matches the turbine blade temperature.

  • With a range of available body materials, the VBSE valve can be used for the main steam pressures and temperatures of today‚Äôs most advanced single and double reheat thermal power plants.
  • Specially designed for modern ultra supercritical power plants load ramping and trip case requirement.
  • Forged body design with flow-to-close flow pattern.
  • Pressurised seal bonnet design allowing for greater reliability at high pressures.
  • Can be equipped with hydraulic, electromechanical or pneumatic actuator.
  • Seal welded seat with integral first stage pressure reduction tube allowing for quick maintenance and replaceable features.
  • Spring loaded water injection nozzles.
  • Integral inlet nozzle upon request.
  • Different plug designs available.
