The 2025 Zhejiang Machinery Industry Science and Technology Award winners have been announced. Lianggu Valve Group won the third prize for its innovative research and development of the <Internal Pressure Self-Sealing Gate Valve for High-Pressure Hydrogenation Units>. This honor not only highly recognizes Lianggu Valve's innovation in the industry but also affirms the company's long-term commitment to technological breakthroughs and quality improvement.
With the widespread application of high-pressure hydrogenation processes in the oil refining industry, including hydrorefining desulfurization and hydrocracking, the industry has placed higher demands on the performance and reliability of high-pressure hydrogenation valves. High-pressure hydrogenation processes not only involve high temperatures (up to 500℃), high pressures (nominal pressure Class 600~Class 2500), and flammable and explosive gaseous media, but also the presence of hydrogen sulfide, which greatly tests the selection of valve materials and their sealing performance.
To cope with this harsh operating condition, Lianggu Valve Group meticulously designed and manufactured an internal pressure self-sealing gate valve for high-pressure hydrogenation units. This product employs an advanced self-sealing structure design, utilizing media pressure to self-seal, significantly improving the valve's service life and stability while ensuring its sealing performance and corrosion resistance. Its unique design allows it to maintain excellent performance even in high-temperature, high-pressure environments and with corrosive media.
Lianggu Valve Group adheres to comprehensive quality control from design to production. Through rigorous testing and trials, we ensure that every valve meets factory standards, guaranteeing its stability and safety at customer sites. Lianggu Valve has obtained numerous domestic and international certifications, including the National Special Equipment TS (A1) Level Manufacturing License, ISO system certification, 15848 micro-leakage certification, fire protection certification, and API certification, fully demonstrating the high quality and global competitiveness of our products.
Behind these honors lies Lianggu Valve Group's unwavering pursuit of technological innovation. The company will continue to dedicate itself to technological research and development, constantly improving product quality and driving technological progress and innovation in the industry. In the future, Lianggu Valve will continue to provide customers with more reliable products, contributing to the sustainable development of global industry.
