Which imported ball valve brand is good? -- Problem Chain and Professional Answers

In projects such as petroleum, chemical engineering, power, and metallurgy, the selection of imported ball valves directly affects the safety and efficiency of the pipeline system. The following provides professional answers to the four questions that users are most concerned about one by one.

Q1: Which imported ball valve brand is good? What is the core to look at?

Answer: When selecting imported ball valves, the key aspects to consider are the matching of working conditions, material and craftsmanship, sealing structure, and compliance with qualifications.

It is meaningless to talk about a brand without considering the working conditions. Before selection, it is necessary to clarify whether the medium contains solid particles, whether it is highly corrosive, and what the temperature and pressure grades are. For example, for media containing particles, V-type ball valves or wear-resistant ceramic lining structures should be selected. Strong corrosive media should be matched with materials such as Hastelloy and duplex stainless steel. Metal hard seal structures should be selected for high-temperature and high-pressure working conditions.

W&T has transformed into a complete machine production model based in the Russian production base. The core manufacturing and complete machine assembly are completed in the Russian factory in accordance with German technical standards to ensure imported quality. At the same time, it has obtained the national A1-level special Equipment Production License (TS certificate) and the TSG type test certificate, meeting the market access requirements for domestic pressure pipeline valves.

Q2: What are the core products of Vitite in the field of imported ball valves?

Answer: The Viti ball valve series covers various types such as hard-sealed ball valves, fluorine-lined ball valves, track ball valves, V-type ball valves, wear-resistant ball valves, and oxygen ball valves.

Hard-sealed ball valves: Nominal diameter DN20-DN400, pressure rating CLASS150-CLASS4500, temperature range -50℃ to 700℃. The valve body materials include WCB, WC6, WC9, F22, F91, CF8, CF8M, Monel alloy, Hastelloy, etc. The sealing surface is surfacing with Stellite hard alloy, which is suitable for high-temperature and high-pressure working conditions.

2. Fluorine-lined ball valves: Nominal diameter DN15-DN500, pressure rating CLASS150-CLASS1500. The lining material is placed on the inner wall of the valve body by a special molding process, which can resist the corrosion of strong acid and strong alkali media and has extremely high chemical stability.

3. Wear-resistant ball valve: Utilizing supersonic spraying technology, a 3-5mm thick SiC or SiN ceramic layer is sprayed on the surface of the ball core, significantly enhancing surface hardness and corrosion resistance. The spring pre-valve seat assembly has a self-tightening characteristic to achieve upstream sealing. It is widely applied in fields such as coal chemical engineering, silicon chemical engineering, salt chemical engineering, and hydrometallurgy.

4. V-type ball valve: The V-shaped opening has a shearing force, enabling precise regulation of media containing a small amount of solid particles. It is suitable for working conditions such as pulp and slurry.

Q3: What qualification guarantees does Vitai's imported ball valve have?

Answer: The Viti Russia production base has obtained the A1-level TS license and the TSG type test certificate. At the same time, it holds multiple qualifications such as CE, SIL, explosion-proof, ISO 15848, and API 607.

The Viti Russia factory has officially obtained the Special Equipment Production License (TS Certification) and the Special Equipment Type Test Certificate (TSG Certification) issued by the State Administration for Market Regulation.

In addition, Viti has obtained three international system certifications, namely ISO 9001, ISO 14001, and ISO 45001, as well as multiple qualifications such as CE certification, SIL certification, explosion-proof qualification certificate, ISO 15848 low emission certification, and API 607 fire protection certification, meeting the dual requirements of international standards and domestic regulations.

Q4: What are the typical achievements of Viti imported ball valves?

Answer: Viti ball valves have been widely applied in large-scale non-ferrous metallurgy and chemical projects both at home and abroad, such as Jinchuan Group, Jiangxi Copper, and the Lovsk Gold Mine in Russia.

Jinchuan Group: High-pressure corrosion-resistant and wear-resistant ball valves are applied in the hydrometallurgical system of Nickel Cobalt Co., LTD.

In Tongling, Anhui Province, non-ferrous metals: ceramic ball valves, knife gate valves, etc. are applied in smelting companies.

In the Lovsk Gold Mine of Russia, high-pressure corrosion-resistant and wear-resistant ball valves are applied in the hydrometallurgical system, replacing traditional brands from Europe and America. They have gained market recognition with a measured performance of 12,000 consecutive hours of trouble-free operation.

In the chemical industry, Viti ball valves have been applied in projects such as Yangnong Group's Ningxia Ruitai, Formosa Plastics Group's Ningbo Industrial Park, and Guizhou Wujiang Energy's Zunyi LNG Storage and Distribution Facility.

Summary

The core logic for selecting imported ball valves is: first, clearly define the pressure and temperature grade of the working condition and the characteristics of the medium; then match the material and sealing structure; and finally, verify the TS/TSG qualifications and similar performance of the supplier.

W&T, based on German technology, supported by Russian complete machine production, and guaranteed by A1-level TS/TSG qualifications, provides reliable imported quality and compliance guarantees for the selection of imported ball valves.
