2008: Our company entered the API-standard valve manufacturing industry, marking the beginning of its journey in the valve sector.
2010: In response to the needs of American clients, we began researching API 622 low-leakage graphite sealing packing, focusing on improving valve sealing performance.
2010 - 2019: Over nearly a decade, we have collaborated extensively with leading research institutions, including Lanzhou University of Technology’s National Key Friction Laboratory, Ningbo Institute of Materials, East China University of Science and Technology, and Shanghai Institute of Ceramics. Together, they conducted in-depth analyses of low-leakage graphite sealing technology and the underlying causes of sealing failure, striving to overcome technical challenges and enhance product quality.
2019: We obtained our first TÜV-witnessed API 622 certification, signifying the achievement of international recognition for its low-leakage graphite sealing technology.
2019 - 2024: With third-party verification from TÜV SÜD and TÜV Rheinland, we continued to advance and secured multiple authoritative certifications, including API 622, ISO 15848-1, TA-LUFT, API 624 and API 641. During this period, nearly 500 valves underwent rigorous testing, covering gate valves, globe valves, and ball valves ranging from 1/2 Inch to 20 Inch. The tests spanned extreme temperature conditions from 400°C to -196°C and pressure ratings from Class 150 LB to 2500 LB, fully validating the reliability and stability of our valve products.
2025: Under TÜV Rheinland's witness, our company obtained ISO 15848-1 CC3 certification, further solidifying its technological leadership and industry position in valve manufacturing.
In China's current valve manufacturing industry, large-scale machining is no longer the primary challenge. The real bottleneck in producing high-quality valves lies in the lack of in-depth research into fundamental disciplines, particularly the mechanical properties of non-metallic materials, surface coating processes for sealing components, and friction/wear mechanisms. These factors are the true keys to advancing valve performance.
Our team brings together nuclear-grade sealing engineers, valve specialists, advanced materials scientists, and electromechanical engineers. As an integrated innovation company, we are committed to:
Delivering superior valve products through precision engineering
Optimizing manufacturing processes for enhanced efficiency and reliability
Partnering with third-party testing labs to validate safety and performance beyond industry standards
We're redefining valve technology by bridging the gap between academic research and industrial application.
