Hydraulic Blind Valve Application in the Steel Industry

Environment of continuous tightening of environmental protection policies, the metallurgical industry is undergoing a profound technological change. As one of the key equipment, the hydraulic blind plate valve is becoming a new engine to promote the green development of the industry with its excellent performance.

Policies lead technology upgrades

The industry’s requirements for the sealing performance of gas systems have reached unprecedented heights. Due to its inherent technical limitations, traditional gate valves can no longer meet the current stringent environmental protection standards. The hydraulic blind plate valve using hydraulic drive technology, through its innovative metal hard seal design, not only achieves rapid opening and closing in seconds, but also ensures the complete sealing of the gas medium. “This renovation has brought us real benefits.” Manager Wang of the Equipment Department of a Steel Group said, “After the new valve was put into use, the system leakage rate dropped to below 0.1%, fully meeting the ultra-low emission requirements. More importantly, automated operation has increased work efficiency by more than 80%.”

Technological innovation solves industry problems

The special working conditions in the metallurgical industry place extremely high demands on equipment reliability. Faced with multiple challenges such as high temperature, high pressure, and corrosive media, domestic valve manufacturers continue to break through technical bottlenecks. The newly developed high-pressure hydraulic blind plate valve adopts a two-way sealing structure and a special anti-scouring coating. It exhibits excellent stability under a working pressure of 10MPa and a high temperature of 400℃. “The service life of our products is three times longer than that of traditional valves.” The technical director of a valve company said, “This is mainly due to breakthroughs in material technology and optimization of structural design.”

Intelligent transformation is accelerating

It is worth noting that the integrated application of IoT technology is injecting new vitality into traditional valves. By integrating sensors and remote control systems, real-time monitoring and intelligent regulation of equipment status are achieved. This innovative achievement has received widespread attention at the recent Shanghai International Environmental Protection Exhibition and has been piloted in many leading companies. “The intelligent valve system makes our operation and maintenance work more accurate and efficient.” An engineer from a pilot company said, “Now we can grasp the operating status of the valve at any time and discover potential problems in advance.”

Continuous expansion of application areas

In addition to the steel industry, hydraulic blind plate valves also show great potential in the coking field. A coking enterprise successfully solved the gas leakage problem that had troubled it for many years by upgrading its equipment, and it is expected to reduce VOCs emissions by more than 50 tons per year. “This valve has brought a qualitative leap in our environmental protection work,” said the head of the environmental protection department of the enterprise.

Looking to the future

With the implementation of the new national standard, the technical specifications of hydraulic blind plate valves will be further improved. Industry experts generally believe that the deep integration of electro-hydraulic integration technology and intelligent operation and maintenance systems will open up a broader space for product applications. “This is not only a technological upgrade, but also a change in development concepts.” An industry observer pointed out, efficient and intelligent environmental protection equipment will surely become an important force in promoting industrial green transformation.”
