Overview
Ensuring Turbine Stability: Advanced Turbine Bypass Solutions
Angle Type Turbine Bypass Valve
Steam Turbine Bypass is a severe-service Steam Conditioning application due to critical requirements of fast opening, perfect sealing and frequent start-up from cold or warm conditions. Turbine Bypass Valves provide system protection to upstream and downstream plant components and sometimes perform these tasks in a fraction of a second.
Turbine Bypass Valves are subjected to large thermal stresses due to the rapid and sudden opening of the valve during a turbine trip sequence.
These valves are generally manufactured from forged materials, allowing for higher strength and durability compared to equivalent cast materials.
Optimize your turbine's efficiency and extend lifespan with our precision-engineered bypass valves.
