Our company, as a pioneering professional in the research, development, and manufacturing of valves for extreme conditions such as high temperature and pressure, ultra-low temperature, and large diameters, is also a comprehensive service provider of valve solutions across all industries. Headquartered in Jinshan Industrial Zone, Shanghai, China, we have been deeply rooted in the valve industry for over two decades. Through relentless efforts and remarkable development, we have risen to become a key enterprise in China's valve industry. We specialize in enhancing our manufacturing capabilities and innovation in specialized valves for extreme operating conditions, dedicated to providing customers with comprehensive and customized fluid control solutions. We are a large-scale valve enterprise integrating scientific research and development, testing and inspection, manufacturing, and marketing. Our product line covers six major categories, encompassing over 1000 specifications and varieties. Beyond conventional valves, we have achieved patent breakthroughs in dozens of high-end special valves, including high-pressure hydrogen-resistant valves, ultra-low-temperature special valves, high-temperature and high-pressure nuclear valves, high-temperature and high-pressure oxygen valves, natural gas regulating valves, molten salt throttling valves, and more. These special valves are widely used in extremely harsh environments, such as temperatures up to 1000° C, pressures of 4500LB, ultra-low temperatures of -196° C, and high-particle transportation scenarios. Materials range from cast iron, carbon steel, stainless steel, duplex steel, to special alloys, catering to the unique needs of various industries. We have established a comprehensive enterprise standardization management system, adopting world-leading precision casting technology combined with modern electronic detection systems.
