API Zirconium B752 702C Flanged Wedged Gate Valve
Wedge gate valve is a type of gate valve. It is named after the fact that its sealing surface is at an angle to the vertical centerline, i.e. the two sealing surfaces are wedge-shaped. Wedge gate valves are divided into rising stem gate valves and rising stem gate valves, wedge single gate valve and wedge double gate valve.
Zirconium gate valves have excellent corrosion resistance in chemical processing industries, such as organic and inorganic acids, salt solutions, strong alkalis, and some molten salts. Zirconium, as a peculiar metal with unique physical and chemical corrosion resistance, has been widely used in special and strict processes, and has irreplaceable applications in fields such as nuclear industry, aerospace, aerospace, and civil chemical industry.
