Shanghai, August 19, 2024, Shanghai Pudong Hanwei Valve Co., Ltd. successfully delivered a RVI-850 24-way rotary valve to the expansion project of a new material company in Jiangsu. This delivery is the second of the same type of product ordered by the company, after Hanwei valve delivered the same specifications of the rotary valve has been running smoothly so far.

"24 way rotary valve" is Hanwei valve completely independent design and production, with 100% independent intellectual property rights of the core product. The smooth and rapid delivery once again demonstrated Hanwei valve's design and manufacturing capability of high-end core valve products in complete sets of equipment and petrochemical devices, and also once again proved and consolidated Hanwei Valve's core position in the rotary valve industry of simulated moving bed continuous adsorption separation device.

Technological breakthrough and localization

"24 way rotary valve" is the core product of Hanwei valve, is a set of mechanical, hydraulic, electronic, instrument automation control and chemical process integration of high-tech products. Hanwei valve from the 1970s began to pay attention to this product, after years of dedicated research and development, independent research and development in the 1990s and successfully applied to paraxylene (PX) device and linear alkyl benzene (LAB) device, in one stroke to break the long-term technical blockade of the United States, to improve the national energy equipment, petrochemical equipment key valve localization is of great significance. After years of development, the products have been used in many major chemical projects at home and abroad.

The "24 way rotary valve" and the surrounding technology derived from Hanwei valve have been granted a number of invention patents and utility model patents by the National Patent Office. With the localization of national key equipment and technology, innovation and iteration of chemical technology, Hanwei valve and a number of domestic research institutes, universities, design institutes continue to cooperate, in order to meet and adapt to the new needs brought by the new process, Hanwei valve "24 way rotary valve" has been through many technological innovations and upgrades, product application scenarios are more and more extensive.

Product characteristics

After the "24 way rotary valve" was successfully developed 30 years ago, through many years of application, the product has been continuously improved and optimized, excellent performance and advanced design highlight the following remarkable characteristics:

- Integration: The integration of mechanical, electrical, instrumentation, hydraulic and other systems to achieve a high degree of automatic control.

- Compatibility: Suitable for the world's main simulated moving bed continuous adsorption separation process. Can meet a variety of process media systems.

- Automation: The use of advanced computer process control to ensure the efficiency and reliability of the operation.

- Upgradable: Through the upgrading of the production process system, multiple valves can be used in series to achieve a substantial upgrade of process capacity. At the same time, the new process can be realized by optimizing the pipeline design and increasing the quantity of material connection.

Industry impact

The successful delivery of the "24-way rotary valve" has had a profound impact on the entire valve industry. Previously, the 24 way rotary valve was mainly produced by the United States Artisan Company, and was exclusively sold and operated by UOP (United States Global Oil Products Company). The purchase cycle of products was long, the price was high, and trade sanctions, chain break, and intellectual property protection increased many uncertainties. Hanwei valve "24 way rotary valve" product price competitive advantage is obvious, and later operation and maintenance and spare parts cost is lower, can save a lot of foreign exchange for the country. China is the world's most active economy, in order to seize more and higher markets, chemical companies in the new products, new processes, new technology investment is huge, there is also the risk of intellectual property penalties. In the simulated moving bed continuous adsorption separation industry, its core product is the rotary valve. Hanwei valve "24 way rotary valve" not only solves the problem of technical process jam, but also strengthens the awareness of independent intellectual property protection, and eliminates the risk of enterprise investment. With 100% independent intellectual property rights, Hanwei Valve "24-way rotary valve" can fully adapt to the localized procurement needs of chemical enterprises for the core rotary valve of such devices.

Future outlook

"24 way rotary valve" not only improves the technical level of domestic valve manufacturing enterprises, but also provides valuable experience for other domestic enterprises, and encourages more enterprises to devote themselves to the independent research and development and innovation of high-end equipment. Hanwei Valve continues to strengthen exchanges and cooperation with domestic and foreign partners, expand the influence of China's high-end manufacturing in the world, and jointly promote Chinese-style modernization and high-quality development of China's economy.
