Introduction In industrial fluid control systems, gate valves, as a type of shut-off valve, have long played a key role in opening and closing operations. With increasingly complex operating conditions, higher demands are being placed on valves in terms of corrosion resistance, wear resistance, and service life. Among the many available materials, duplex stainless steel (ASTM A995 5A) combi...
