DRE140CH - High Pressure Turbine Bypass Valve
The DRE140CH valve combines high-pressure steam reduction and desuperheating, ensuring efficiency in cyclic operations of power plants.
Combines high-pressure steam throttling and in-body desuperheating for precise control.
Reduces noise and prevents thermal shocks with a multi-function contoured cage.
Compact, robust design allows for easy maintenance and long-term durability.
Features
The DRE140CH High-Pressure Bypass Valve is designed for steam conditioning in fossil-fired power plants under subcritical and supercritical steam conditions. It combines high-pressure steam throttling with in-body desuperheating to ensure precise temperature and pressure control. The valve features a wing-type plug for noise reduction, a multi-function contoured cage to prevent thermal shocks, and a spherical body for minimal stress. With a compact, robust design and replaceable components, the DRE140CH valve offers durability, efficient operation, and easy maintenance in demanding cyclic applications.
