316L Stainless Steel Valve Seat Support Ring – Revised Version

316L Stainless Steel Valve Seat Ring – Durable Support for Precision Valve Sealing

This valve seat ring is made from 316L stainless steel and used as a structural support part behind the sealing seat in industrial valve assemblies. Its role is to provide consistent compression, accurate positioning, and a stable interface between the seat and the valve body.

We machine this component from solid 316L bar or forged blanks using CNC lathes, ensuring tight tolerances and a smooth finish. The surface that contacts the sealing element is polished to avoid damage to soft seals like PTFE or graphite and to ensure a uniform load distribution. For metal-to-metal sealing applications, the ring maintains concentricity under pressure to help prevent uneven wear or leakage.

    • Material & Performance

      316L stainless steel is widely used in valve manufacturing for its excellent corrosion resistance, especially in applications involving chlorides, acids, or steam. The low carbon grade helps avoid carbide precipitation during welding and extends the service life in corrosive and high-temperature environments. It’s suitable for both general-purpose and sanitary systems, including chemical processing, clean water, and offshore equipment.
