Power Plant
1. Industry Background
In modern power generation systems, valves play a critical role in controlling, regulating, and protecting fluid systems. From thermal power plants to nuclear, hydro, and renewable energy facilities, valves are essential for ensuring safe, efficient, and reliable operation across multiple processes — including steam generation, water circulation, chemical treatment, and fuel delivery.
Operating under high temperature, high pressure, and corrosive environments, valves in power plants must deliver long-term sealing reliability, structural strength, and precise control performance to maintain system stability and safety.
2. Key Challenges in Power Plant Applications
High Temperature and Pressure
Steam pipelines and boiler systems often operate above 540°C and 250 bar, demanding materials with exceptional heat and pressure resistance.
Complex and Corrosive Media
Steam, feedwater, chemical fluids, and ash slurry can cause erosion, corrosion, and leakage in standard valves.
Frequent Operation and Precise Control
Control valves and drain valves require high cycling capability and fast response to maintain flow stability and prevent pressure fluctuations.
System Safety and Reliability
Valve failure or leakage can lead to unplanned shutdowns or safety incidents, making reliability a top design priority.
