SDF's rapid-closing extraction check valves achieve complete closure within 0.5 seconds, providing maximum protection for steam turbines by rapidly isolating the extraction system. For larger valve sizes, SDF employs counterweight designs that balance valve disc gravitational torque, assist in valve opening, and maintain operational stability while reducing vibration.
During manufacturing, SDF applies advanced Finite Element Analysis (FEA) and computational fluid dynamics to optimize performance under extreme conditions. Premium materials and precision machining ensure long-term reliability in high-temperature, high-pressure environments.
SDF's extraction check valves have been successfully deployed at major projects including Guangdong Guohua Taishan Power Plant and Datang International Chaoshan 300MW Power Plant. A Taishan project engineer commented: "SDF's check valves demonstrate exceptional reliability, response speed, and service life, significantly reducing unplanned downtime and maintenance costs."
With continued growth in thermal power plant construction, SDF remains committed to refining extraction check valve technology to support safer, more efficient power generation.
