Domestic Cryogenic Ball Valve Technology Achieves New Breakthroughs, Boosting Efficient Development of Clean Energy
Recently, Chinese valve manufacturing enterprises have made a series of technological breakthroughs in the field of cryogenic ball valves. Multiple products have been successfully applied in clean energy projects such as liquefied natural gas (LNG), providing a reliable "Chinese solution" for fluid control under extreme operating conditions.The main Ball valve product names of China Ball valve Network include:PP-R Copper Ball Valve( External Wire Single Head Type)，PP-R Copper Ball Valve(Double Heads Type)，Q11SAF-64 Inner Thread Forged Steel Meter Ball Valve，Q13SAF-64 Inner Thread Angle Meter Ball Valve，Q347F ANSI Stainless Steel Fixed Ball Valve，Q41F Telescopic Ball Valve，Q91SAF-64 Sleeve Meter Ball Valves，Q94SAF-64 Sleeve Three-way Meter Ball Valve Ball Valve News
Cryogenic ball valves are core equipment in the LNG industry chain, requiring zero-leakage sealing and long-term stable operation in ultra-low temperature environments ranging from -196°C to -162°C. For a long time, this market was dominated by foreign brands. To break this monopoly, domestic companies have increased their R&D investment, overcoming industry challenges such as material embrittlement and sealing failure due to thermal contraction.
In terms of technological innovation, the low-temperature top-entry C-type ball valve independently developed by Wuxi Smart Auto-control successfully passed a -196°C liquid nitrogen immersion test recently. It operated smoothly after deep cryogenic treatment and obtained a special equipment type test certificate. Suyan Valve, on the other hand, adopted a composite structure of nickel-based alloy and 316L stainless steel, enabling the valve to operate continuously for 8,000 hours under -196°C conditions with zero leakage, with performance exceeding international standards by 30%.
Furthermore, companies like Chenggao Valve have obtained patents for "online disassembly and assembly cryogenic ball valves." Through a unique sealing surface design, they have reduced processing difficulty and achieved online maintenance without stopping operations, greatly improving the continuity of industrial production.Ball Valve
Currently, these domestically produced cryogenic ball valves have been successfully applied in national key projects such as the Binhai LNG Cold Energy Demonstration Zone and large LNG carriers, with the localization rate exceeding 90%. Industry experts state that with the advancement of the "dual carbon" strategy, the market demand for cryogenic valves will continue to grow, and the pace of localization is expected to accelerate further.
