TEJI Valves at Marintec China 2025

On December 2nd, the global maritime industry’s “trendsetter”—Marintec China 2025—opened at the Shanghai New International Expo Centre. Amidst the wave of green transformation in the maritime industry, TEJI Valve Group showcased its cryogenic ball valves and marine copper valves, demonstrating its commitment to sustainable development through innovative technologies.

Notably, in recent years, TEJI Valve Group has obtained certifications from three major international authorities: the China Classification Society (CCS), the American Bureau of Shipping (ABS), and Bureau Veritas (BV). Classification society certification is a quality “passport” in the shipbuilding and marine engineering equipment field, with audit standards covering the entire chain of material performance, manufacturing processes, and safety and reliability. This signifies that our product quality and technical standards have fully aligned with global maritime industry requirements, laying a solid foundation for expanding into international markets and serving global customers.

Furthermore, driven by “dual carbon” goals, the demand for cryogenic valves in the maritime industry is steadily increasing. TEJI’s cryogenic valves showcased at the exhibition have garnered numerous invention patents, Zhejiang Province’s patent-intensive product certification, and the Zhejiang Provincial Machinery Industry Science and Technology Award. These products enable valve maintenance without shutdown under cryogenic conditions, significantly improving the continuity and efficiency of industrial production.

From its workshops in Yongjia to the depths of the world’s oceans, TEJI Valves consistently prioritizes technological innovation, driving the marine industry towards green, intelligent, and safe development. This exhibition not only demonstrates the core strength of Chinese valve manufacturers but also aims to inject Eastern wisdom into the global marine industry chain through in-depth exchanges with exhibitors from various regions.

The resilient-seal concentric butterfly valve is a common type of valve where the valve stem axis, the center of the butterfly plate, and the center of the valve body are located on the same axis. It uses elastic materials such as rubber for sealing, and the sealing pressure is generated by the elastic force formed by the interference fit between the butterfly plate and the bushing, achieving bidirectional sealing. This valve has a compact structure, low flow resistance, large flow area, and a near-linear flow characteristic, making it suitable for regulating media flow. The sealing ring is removable and replaceable, adaptable to different media requirements. It is commonly used for pipeline media control and flow regulation in petroleum, chemical, and water supply and drainage industries.

Cryogenic Side Entry Triple Offset Butterfly Valve are high-performance valves adapted to low-temperature environments. Their core design utilizes a triple offset structure: the valve stem axis is offset from both the valve body centerline and the butterfly plate center, and the valve seat sealing surface is inclined to the valve body channel axis, achieving torque sealing. The valve body, valve seat, and butterfly plate are made of special materials resistant to low-temperature impact and corrosion, such as stainless steel and alloy steel.

Metal-seated triple offset butterfly valves are valve components used for on/off control and flow control in pipeline systems. They are mainly used in petroleum, chemical, metallurgical, hydropower, and urban heating industries. They can be used in industrial pipelines with a medium temperature ≤425℃ for regulating flow and cutting off fluid.Structural Features The metal-sealed triple-eccentric butterfly valve employs a triple-eccentric design, where the valve stem axis is offset from both the butterfly plate center and the body center. The valve seat rotation axis and the valve body channel axis form an angular sealing structure. This structure includes three eccentric designs: the axis offset from the valve seat centerline, the axis offset from the pipeline centerline, and the valve seat cone tilt. The valve seat sealing ring is typically composed of a soft T-shaped sealing ring and multiple layers of stainless steel sheets. The valve plate sealing surface is overlaid with a corrosion-resistant alloy to form a slanted conical structure.
