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.

• Specially designed for modern ultra supercritical power plants load ramping and trip case requirement.
• Forged body design with flow-to-close flow pattern.
• Available in pressure seal bonnet and bolted bonnet design.
• Can be equipped with hydraulic, electromechanical or pneumatic actuator.
• Seal welded seat with Integral first stage PR tube allowing for quick maintenance and replaceable features.
• Spring loaded water injection nozzles.
• Different plug designs available.
