Zhejiang Pariworld Automation Meter Co., Ltd. has successfully won the contract for the self-operated pressure regulator package of the CNOOC & Shell Petrochemicals Huizhou Phase III ethylene project, a flagship ethylene complex with a total investment of nearly RMB 60 billion and an annual ethylene capacity of 3.8 million tonnes.
The project, which focuses on high-end polyolefins and new materials, sets extremely high requirements on the stability, precision, corrosion resistance, explosion-proof safety, and long-cycle operation of critical control equipment — a benchmark application that puts domestic control valve technology to the test.
Pari World’s self-operated pressure regulators feature an all-mechanical structure that requires no external power or air supply, using the medium’s own energy for automatic regulation. They deliver fast response, precise control, reliable sealing, maintenance-free operation, and low energy consumption, and are well suited to high-temperature, high-pressure, and corrosive working conditions.
Backed by rigorous working-condition validation and third-party testing, Pari World valves are widely applied in petrochemical, coal chemical, oil and gas, and lithium battery industries, and are recognized by customers including CNOOC, Sinopec, and Wanhua Chemical.
This contract marks an important milestone: domestic self-operated regulators have entered the core supply chain of a world-class petrochemical project, further advancing the localization of high-end industrial control valves in China.
