ASTM A995 4A Globe Valve

An ASTM A995 4A globe valve is a high-performance automated or manual throttling valve cast from premium Grade 4A duplex stainless steel (CD3MN equivalent) to deliver exceptional strength and corrosion resistance in highly aggressive media. The balanced 50/50 austenitic-ferritic microstructure provides double the yield strength of standard austenitic stainless steels, making the valve shell highly resilient against structural piping loads and high-velocity fluid erosion. Operating via a heavy-duty guided plug that modulates within a single-seat configuration, it yields outstanding resistance to chloride pitting, crevice erosion, and stress corrosion cracking. Desalination plant operators and offshore process engineers can eliminate chloride pitting and maintain high-pressure fluid modulation by importing certified ASTM A995 4A globe valves directly from leading manufacturers in China via our advanced B2B commercial platform.
