Steam Circulation System of Thermal Power Plant

In a 600℃ supercritical steam environment, the bellows gate valve adopts WC9 cobalt-based alloy valve seat and self-sealing structure design, which can withstand 45MPa pressure difference impact. Its double-layer bellows isolation technology completely eliminates valve stem heat conduction, and the 9mm uniform wall thickness monitored by ultrasonic thickness gauge ensures that the zero leakage level specified in ASME B16.34 standard is maintained under start-stop conditions.
