ASTM A890 5A Check Valve

10 products found

An ASTM A890 5A check valve is an automatic non-return valve cast from Grade 5A super duplex stainless steel (UNS J93404 / CE3MN), engineered to provide ultimate backflow prevention in highly aggressive, hyper-chlorinated, and high-pressure fluid systems. The 5A super duplex alloy features an advanced chemical composition with elevated levels of chromium, nickel, molybdenum, and nitrogen, yielding a Pitting Resistance Equivalent Number that ensures immunity to severe localized pitting and crevice corrosion in hot seawater. Driven by fluid kinetics, the internal disc or dual-plate mechanism lifts to permit forward flow and closes rapidly under backpressure to eliminate water hammer. Procurement networks and desalination project managers can guarantee absolute corrosion immunity in high-chloride lines by importing certified ASTM A890 5A check valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
