NBSE Low Pressure Turbine Bypass Valve

NBSE Low Pressure Turbine Bypass Valve

The NBSE 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 dump steam from reheat lines to condenser until the steam temperature matches the turbine blade temperature.

With the range of available body materials, the NBSE valve can be used for steam pressures and temperatures of today’s most advanced single and double reheat thermal power plants.
