As the power battery industry continues to expand production capacity, downstream sectors are demanding increasingly higher standards for product quality and consistency. Electrode coating and electrode sheet drying are critical steps in cell manufacturing, requiring precise temperature control.
Fluctuations in coating temperature can affect slurry rheology, while uneven temperatures during drying can lead to variations in electrode sheet moisture content, ultimately impacting the consistency of cell performance.
Thermal oil and steam systems handle essential heating tasks for the entire production line. As key control components within these thermal energy systems, valves—specifically their sealing reliability and regulation precision—directly influence system operational stability and temperature control effectiveness.
Coordinated Valve Operation
To meet the specific operational requirements of the project, VMV supplies a range of valve products for the thermal oil and steam systems.
Bellows-Sealed Valves
These valves utilize a multi-layer stainless steel bellows sealing structure, effectively mitigating the risk of external leakage caused by media permeation under high-temperature thermal oil conditions. Thermal oil systems typically operate between 200°C and 350°C; while standard packing seals are prone to aging due to prolonged high-temperature exposure, bellows seals—featuring a dual-sealing structure—deliver superior sealing reliability and reduce long-term maintenance needs.
Other Valve Types
Ball valves handle pipeline opening, closing, and flow switching.
Control valves regulate steam flow, with their precision directly impacting the response speed of the temperature control system.
Safety valves automatically relieve pressure during system overpressure events, ensuring safe equipment operation.
Each valve performs its specific function, collectively supporting the stable operation of the thermal energy system.
From Products to Projects
Stable operation relies equally on rigorous manufacturing and inspection processes.
VMV subjects every product to pressure and sealing tests, conducts spectral analysis on raw materials to verify composition, and performs additional non-destructive testing (NDT) on products intended for high-temperature applications. By strictly executing every inspection step and ensuring reliability in every detail, VMV guarantees the long-term, stable performance of its products under actual operating conditions.
For over two decades, VMV has focused deeply on steam and thermal energy systems. Its products are widely used across industries such as chemicals, textiles, pharmaceuticals, and food processing. In the new energy lithium-ion battery sector, the company has served major enterprises—including CATL, BYD, EVE Energy, and Sunwoda—accumulating extensive practical project experience.
From thermal oil and steam to hot water systems, long-term project applications have yielded a wealth of data on operating conditions and expertise in equipment selection. To address the specific risks and sealing requirements associated with varying media, temperatures, and pressures, VMV consistently bases its approach on actual operating conditions to deliver highly reliable valve solutions for its customers.
Conclusion
As the new energy industry continues to evolve, thermal energy systems demand higher standards of safety, stability, and energy efficiency.
Looking ahead, VMV remains committed to the steam and thermal energy sectors. Leveraging reliable valve products and proven expertise in real-world applications, the company will continue to support the safe, stable, and efficient operation of a wide range of industrial projects.
