The new favourite of the metallurgical industry: blind valve

In recent years, with the continuous improvement of the metallurgical industry’s requirements for safe production and environmental protection, blind valves, as an efficient and reliable pipeline partition equipment, are gradually becoming an important choice for metallurgical enterprises. With its excellent sealing performance, high temperature and high pressure resistance and convenient operation, the blind valve shows a wide range of application prospects in steel smelting, non-ferrous metal processing and other fields, providing strong support for enterprises to achieve green and efficient production.

The blind valve has significant advantages to ensure the safety of metallurgical production.

In the metallurgical production process, high temperature, high pressure and corrosive media pose severe challenges to the safety of the pipeline system. Traditional valves are prone to wear and leakage and other problems in long-term use, while the blind valve adopts a unique blind structure design, which can completely cut off the flow of medium, ensure absolute safety during overhaul and maintenance, and effectively avoid safety accidents caused by valve failure.

Intelligent blind valve helps metallurgical automation.

In 2024, the electric intelligent blind valve will realise remote control and status monitoring through Internet of Things (IoT) technology, shorten the valve opening and closing time to 15 seconds, and link with the DCS system to improve the emergency shut-off efficiency of gas pipelines.

Key project application cases of the blind valve

The Indonesian steel blast furnace project adopts wear-resistant ceramic lined blind valve to solve the problem of blast furnace gas dust (containing iron ore particles) scouring the valve, and the service life is increased by 3 times.

In 2023, in Baosteel’s hydrogen-based shaft furnace project, a hydrogen-embrittlement blind valve was selected for the safe isolation of hydrogen medium, and the valve passed the ISO15848-1 strict leakage certification.

The market demand is growing, and the domestic blind valve technology is meeting the development opportunity.

Through technological innovation, domestic valve manufacturing enterprises have gradually broken the market monopoly of foreign brands, developed high-temperature resistant and corrosion-resistant blind valves suitable for extreme working conditions, and successfully applied them to many large metallurgical enterprises.

Epilogue

The wide application of blind valves in the metallurgical industry marks a new level of industrial equipment in China. With the continuous progress of technology and the expansion of market demand, Zhengzhou Jinggong Valve Co., Ltd produces blind valves with high standards and strict requirements, and will continue to provide a solid guarantee for the safe, efficient and green development of the metallurgical industry, and help enterprises achieve higher quality production goals.
