I.Specification Parameters

  • The nominal diameter (DN) is precisely 300mm. Designed meticulously based on fluid mechanics principles, the relatively large flow passage cross-sectional area under this size enables the medium to pass through smoothly with low resistance, fully meeting the urgent needs of large-scale industrial installations for large-flow transmission. It is widely applicable to large-scale fluid transfer scenarios such as in the chemical and petroleum refining industries.

  • The nominal pressure (PN) firmly reaches 25 bar. Manufactured in accordance with strict pressure test standards, each ball valve undergoes high-pressure sealing and strength tests before leaving the factory, ensuring safe and continuous stable operation in complex medium- and high-pressure working conditions, such as in long-distance petroleum pipelines and pressure pipelines in large chemical reaction devices.


II.Material Characteristics

  • The selected forged F316L stainless steel material contains a high proportion of alloy elements such as nickel and chromium. Nickel endows the material with excellent intergranular corrosion resistance, while chromium forms a dense passive film to strengthen oxidation resistance. With dual protection, it exhibits outstanding resistance to various strongly corrosive media, ranging from chlorine-containing solutions to acidic chemical raw materials, significantly prolonging its service life and reducing equipment replacement frequency.

  •  By using advanced forging technology, the steel is repeatedly forged and shaped under high temperature and pressure. The internal grains are refined, and the structure is dense and uniform. Compared with the pores, porosity and other defects that are likely to occur in traditional casting, the strength of forged F316L components is increased by about 30%, and the toughness is enhanced by nearly 25%, greatly reducing the risk of leakage and laying a solid foundation for the reliable operation of the system.


III.Structural Design

  • The innovative 3PC three-piece structure features a modular design for the valve body, bonnet and ball assembly. During installation, each component can be accurately docked, and during maintenance, the damaged parts can be quickly disassembled and replaced. Compared with the one-piece valve structure, the maintenance time is reduced by about 40%, and the labor cost is reduced by nearly 35%, showing obvious advantages in emergency repair scenarios.

  • The professional gear operation mechanism is carefully matched to the operating torque required by the large-diameter ball valve. With an optimized transmission ratio design, when the operator turns the handwheel, power is smoothly and accurately transmitted through the gear set to achieve a rapid and precise opening and closing of the ball from 0 to 90 degrees. The opening and closing time is 20% shorter than that of the manually directly driven ball valve, effectively improving the operation efficiency and control accuracy and ensuring precise regulation of the process.


IV.Application Fields

  • It is deeply applied in the petrochemical field. From the gathering and transportation pipelines in crude oil extraction to the high-temperature and high-pressure reaction material transportation in refineries, the ball valve precisely controls to ensure smooth and safe processes and prevent safety accidents and environmental pollution caused by medium leakage.

  • In the power industry, it is mainly applied to the turbine cooling circulating water system and the high-temperature and high-pressure steam transmission network. With excellent sealing and pressure resistance, it guarantees the stable operation of power generation equipment and avoids shutdown losses caused by valve failures.

  • In industries with high cleanliness requirements such as food and beverage and pharmaceuticals, the F316L material meets strict hygienic standards. It has a smooth surface that is easy to clean and effectively prevents bacteria growth and material contamination. It escorts the production of high-quality products throughout the process, ensuring precise control of material flow from raw material introduction to finished product packaging.


V.Quality Control

  • A full-process quality traceability system has been established. From the composition test reports of raw material procurement to the process parameter records of forging, machining and assembly, and then to the performance test reports of finished products leaving the factory, all are entered into the database to ensure that the quality of each ball valve can be traced back to its source and problems can be investigated.

  • Advanced non-destructive testing technologies such as ultrasonic flaw detection and magnetic powder flaw detection have been introduced to conduct 100% detection on key components such as the valve body and the ball, discovering internal tiny defects in advance and repairing them in time to ensure that the product delivery quality reaches the international first-class level.
