Valves are indispensable critical equipment in power generation systems, mainly used in the following processes:

Thermal Power Systems

◆ Main steam systems: High-temperature, high-pressure gate valves (P54, 550°C)

◆ Feedwater systems: Wear-resistant control valves

◆ Condensate systems: Corrosion-resistant stainless steel valves

Nuclear Power Systems

◆ Reactor coolant systems: Nuclear-grade gate valves (RCC-M standard)

◆ Containment isolation systems: Fast-closing valves (response time <2 seconds)

◆ Radioactive waste treatment: Zero-leakage diaphragm valves

Key Application Features

◆ Ultra-supercritical parameter valves (31MPa/620°C)

◆ Radiation-resistant material valves

◆ Explosion-proof electric actuators

Special Technical Requirements

◆ Seismic performance (IEEE 344 standard)

◆ Nuclear-grade certification (ASME III certification)

◆ Long-life design (40-year service life)

Power plant valves must comply with strict standards such as ASME and GB, as their reliability directly affects the safe operation of power plants. With the development of new energy sources, valve technology continues to advance to meet increasingly demanding working conditions.
