The DN400 PN25 CF8 gate valve body casting is engineered for high-pressure and large-diameter applications, with a nominal diameter of 400mm (DN400) and a pressure rating of PN25. Made from CF8 stainless steel (equivalent to ASTM A351), it offers good resistance to pitting and stress corrosion cracking. The casting process ensures uniform grain structure and mechanical strength, critical for industrial valves used in power plants, petrochemical, and water treatment systems. Each casting undergoes non-destructive testing (NDT) to detect any internal defects. The design allows for easy integration with actuation systems, providing reliable flow control in demanding environments.
