en.Wedoany.com Reported - Zhejiang Paiwo Automatic Control Instrument Co., Ltd. from China, leveraging its reliable product performance, mature engineering applications, and stringent quality control system, has successfully won the bid for the self-operated regulating valve section of CNOOC and Shell Petrochemicals Company's Huizhou Phase III Ethylene Project. This victory means providing critical fluid control equipment for this world-class ethylene engineering project.
The CNOOC and Shell Huizhou Phase III Ethylene Project involves a total investment of nearly 60 billion yuan. Upon completion, its total ethylene production capacity will reach 3.8 million tons per year, making it a globally leading, technically stringent integrated ethylene base. Focusing on high-end polyolefins and new materials, the project supports the green petrochemical industry upgrade in the Guangdong-Hong Kong-Macao Greater Bay Area and contributes to the realization of the national "dual carbon" goals. The project imposes extremely high requirements on the stability, precision, corrosion and explosion resistance, and long-term operation of key automatic control equipment, serving as a benchmark scenario to test the technical capabilities of domestic control valves.
The winning product is Paiwo's self-operated regulating valve series. Featuring a fully mechanical structure that requires no external power or air supply, it utilizes the medium's own energy to achieve automatic regulation. Its core advantages include sensitive response, precise control, reliable sealing, maintenance-free operation, and low energy consumption. It can adapt to special working conditions such as high temperature, high pressure, and corrosive environments, meeting the demands of long-term continuous production in ethylene plants. The product has passed rigorous operational validation and third-party testing, and is widely used in petrochemicals, coal chemical, oil and gas, lithium battery, and other fields, gaining recognition from outstanding enterprises such as CNOOC, Sinopec, and Wanhua Chemical.
As a national high-tech enterprise, Paiwo focuses on the R&D and manufacturing of special control valves, with deep expertise in high-end valve categories such as self-operated regulating valves, high-temperature and high-pressure regulating valves, and cryogenic valves. Through technological innovation, it aims to break import dependency and continuously increase the market share of domestic industrial control valves in major petrochemical projects. This successful bid for the world's largest ethylene project not only represents high recognition from the client for Paiwo's products and services but also marks the full entry of domestic self-operated regulating valves into the core supply chain of world-class petrochemical engineering.
In the future, Paiwo will use high-standard project delivery as a key focus to ensure the smooth operation of the project. It will continue to deepen its expertise in the high-end process industrial control sector, providing more reliable, intelligent, and green control valve solutions to support the localization of China's high-end equipment and the high-quality development of the petrochemical industry.
