ASTM A890 4A Gate Valve

23 products found

An ASTM A890 4A gate valve is a linear-motion isolation valve cast from grade 4A duplex stainless steel (UNS S31803 / CD3MN), specifically engineered to withstand aggressive, chloride-rich environments. The ferritic-austenitic duplex microstructure provides double the yield strength of standard austenitic stainless steels, along with exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Featuring a wedge-shaped gate that drops perpendicular to the fluid flow, this valve delivers a tight, robust shutoff under heavy mechanical and hydraulic loads. Conforming to design standards like API 600 and ASME B16.34, it is highly sought after for offshore oil and gas production, seawater desalination facilities, marine piping, and chemical processing lines. Procurement teams can lower asset replacement costs in highly corrosive environments by importing durable ASTM A890 4A duplex gate valves directly from certified gate valve manufacturers in China via our B2B digital marketplace.
