Import Balls For Ball Valve — Buy in wholesale FOB from Supplier in China

Balls for ball valves offered by Vasar Valve Co., Ltd cover sizes from 1/4 inch to 48 inches, with pressure ratings spanning 150 lb to 2500 lb classes. The components are manufactured in carbon steel, stainless steel, cryogenic steel, and special alloys including ASTM A105, A182 F304/L, A182 F316/L, Duplex F51, F55, 17-4PH, Inconel 625, 690, 600, 617, 718, 718 SPF, Monel 1400, R-405, K-500, Titanium Gr3, Gr4, Gr7, Incoloy 800, 825, 903, 907, Hastelloy C serial, Hastelloy B, and 09G2S 09Mn2Si GOST grades. Surface treatments include nitridation, electroless nickel plating, chrome plating, tungsten carbide, chrome carbide, Stellite, and Inconel coatings to enhance durability and corrosion resistance.

These balls are engineered for precise sealing and flow control in industrial valve assemblies. Typical industry standards for such components include surface finishes of Ra 0.2 to 0.8 micrometers for tight shutoff, with spherical tolerances held to within 0.03 mm for diameters under 10 inches and 0.05 mm for larger sizes. Materials like A182 F316L are standard for corrosion-resistant applications in oil and gas, chemical processing, and marine environments, while cryogenic steels are used for low-temperature services down to -196°C.

Primary buyers include valve manufacturers, EPC contractors, and maintenance providers in sectors like petrochemicals, water treatment, and power generation. The balls are typically supplied as finished machined components, ready for assembly into split-body, top-entry, or fully welded ball valves. Bulk packaging is standard in wooden crates or palletized boxes, with each unit marked for traceability. Confirm lead times and MOQ directly with Vasar Valve Co., Ltd, as these depend on size, material, and coating requirements.
