5A Austenitic Alloy Steel Lubricated Ball Valve

NSV 5A Austenitic Alloy Steel Lubricated Ball Valve

The NSV 5A lubricated ball valve features a body cast from ASTM A995 CD3MN (5A, UNS S31803) duplex stainless steel which delivering nearly double the strength of standard austenitic grades. This high strength resists deformation and erosion under high pressure, high flow, or abrasive service, significantly extending service life and reducing lifecycle costs. Combined with a grease-sealed metal seat for wear compensation, it ensures dependable shut-off in critical offshore and process applications.
