High Strength Valve Disc for Industrial Valves

Heavy-Duty Forged Sealing Components for Hydropower Valves Forged valve discs are critical sealing components within hydropower and large industrial valves, directly responsible for isolating flow and withstanding system pressure during valve closure. Unlike shafts or stems, the valve disc operates as a pressure-facing element, where material integrity, geometric stability, and surface condition directly influence sealing performance and service life. Our forged valve discs are produced for medium to large hydropower valve assemblies, where high closing force, repeated pressure cycles, and long-term dimensional stability are required. Manufacturing Process Focus Valve discs are manufactured primarily through ring rolling and controlled forging, ensuring uniform circumferential grain flow aligned with pressure-bearing directions. This process significantly enhances resistance to deformation, fatigue, and localized stress concentration under high-pressure sealing conditions. Forging pa…
