The HBSE High Pressure Turbine Bypass Valve is engineered for high-pressure steam systems, directing steam to high-pressure sections such as reheat lines. It plays a critical role in turbine operations, particularly during start-up, shutdown, or load change conditions. In turbine bypass systems, HBSE and NBSE valves can be used alongside steam control valves. This combination enables precise steam control and additional desuperheating via direct spray water injection at the valve outlet—effectively addressing scenarios such as start-up, shutdown, or load fluctuations to ensure the turbine operates safely, stably, and efficiently under these demanding conditions.
