Turbine bypass valves are one of the most difficult applications in a power plant. Keeping these valves operating efficiently and avoiding unexpected failures is critical for plant operation. When ...

The cascading bypass system is perhaps the most common design for managing high-pressure steam in a combined-cycle plant. It is the hot reheat (HRH) bypass valve actuator that defines the valve’s ...

In August’s column, I discussed three-way control valves, their associated bypass pipes, and the importance of a balancing valve being located within the bypass pipe. Such balancing valves are needed ...
