Electric gear blind valve in petrochemical and nuclear power industries

Recently, china valve manufacturers have launched a new generation of electric gear blind valves, which have made major breakthroughs in intelligent control, explosion-proof performance and high sealing. This product is widely used in petrochemical, metallurgical, nuclear power and other fields, and has become a key equipment for industrial pipeline safety isolation, with broad market prospects.

Technology upgrade: intelligence and high sealing performance are the highlights

With the increasing demand for industrial automation, traditional manual blind valves are gradually being replaced by electric gear-driven ones. Electric gear blind valves use the Internet of Things (IoT) remote monitoring technology to monitor the valve switch status, sealing performance and fault warning in real time, greatly reducing the risk of manual inspections.

In addition, in response to the harsh environment of the chemical industry, the explosion-proof electric gear blind valve (compliant with Ex dⅡBT4 standards) optimizes the gear transmission structure to achieve a sealing level of ANSI/FCI 70-2 Class VI, effectively preventing the leakage of toxic and flammable media.

Industry Application:

1.Demand surges in nuclear power and refining
Bulk purchase for large-scale refining and chemical projects: A 10 million ton refining and chemical base in the Middle East recently purchased more than 200 domestic electric gear blind valves (DN300-DN800) for use in residue oil hydrotreating units, marking the entry of domestic high-end valves into the international high-end market.

2.Breakthrough in localization of nuclear power safety equipment
A domestic nuclear power plant used an electric gear blind valve as a nuclear-grade safety isolation valve for the first time. The product passed the IEEE 344 seismic test, providing protection for the independent control of key nuclear power equipment.

Company News: Products Debut at International Exhibitions
At the China International Fluid Machinery Exhibition (CFME), electric gear blind valve products were unveiled and the application of intelligent valves in hazardous environments was discussed. In addition, the US VALVE SUMMIT 2024 will also focus on energy-saving technologies for gear-driven valves to promote innovation and development in the industry.

Experts from the Valve Branch of the China General Machinery Industry Association said: “The intelligence and high reliability of electric gear blind valves are the future development direction. As domestic technology matures, import dependence will be further reduced, and the localization rate is expected to exceed 70% in the next three years.”

The person in charge of ZZJG said: The technological progress of the electric gear blind valve has not only improved the safety and automation level of industrial pipelines, but also provided new opportunities for China’s high-end equipment manufacturing to enter the global market. In the future, ZZJG will also integrate new materials and intelligent control technologies to strive to make this product play a key role in more fields.
