Duplex Steel Gate Valve
6 products found
A duplex steel gate valve is a heavy-duty, linear-motion isolation valve engineered with its body, wedge, and stem fabricated from high-strength duplex stainless steel (such as 2205 or Super Duplex 2507) to handle highly corrosive, high-pressure process lines. The dual-phase metallurgical structure offers outstanding resistance to localized erosion-corrosion, sulfide stress cracking, and acidic environments, outperforming traditional carbon and standard stainless steels in extreme services. When the valve is opened, the stem lifts the wedge entirely out of the fluid path, establishing a straight-through, full-bore conduit with zero flow resistance and minimal pressure drop. Process layout contractors and marine engineering firms can minimize maintenance downtime and secure high-strength line isolation by importing certified duplex steel gate valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
