    Information to be updated

As a professional manufacturer specializing in valve components for the petroleum and natural gas industries, our company focuses on producing customized trunnion valve balls designed for large-diameter and high-pressure valve systems. Our products are widely used in pipelines, oil refining, chemical processing, and other demanding environments where durability and precision are critical.

Each trunnion-mounted ball is produced using advanced CNC machining centers, precision lathes, and strict quality control systems. The surface finish, roundness, and dimensional accuracy of every ball are carefully inspected to ensure reliable sealing performance and smooth operation within the valve body.

We offer complete customization services based on customer drawings and technical requirements, including:

Size range: from small-diameter precision balls to large industrial trunnion balls

Material options: carbon steel, stainless steel, duplex steel, Inconel, and other alloys

Surface treatment: hard chrome plating, electroless nickel plating, tungsten carbide coating, and other anti-corrosion processes

With a modern factory covering thousands of square meters, high-precision production equipment, and a professional technical team, our company has the capability to handle bulk production while maintaining consistent quality. We continuously optimize our machining processes and inspection standards to meet the strict performance requirements of international valve manufacturers.
