The drawbacks in the valve manufacturing industry have led to an increasing gap between domestic and international levels

Valves are pipe fittings used to open and close pipes, control flow, and regulate and control the parameters of the medium being transported (temperature, pressure, and flow rate). Based on their function, they can be divided into globe valves, check valves, control valves, etc. This valve is a control component in fluid delivery systems, with functions such as cutting off flow, regulating it, diverting it, preventing backflow, stabilizing pressure, diverting excess fluid, and releasing pressure. Valves used in fluid control systems come in a wide variety of specifications, ranging from the simplest stop valves to the most complex valves found in automatic control systems. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive substances, mud, oils, liquid metals, and radioactive materials. Valves can also be classified by material into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chromium-molybdenum steel valves, chromium-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and custom-made valves. As a national industry, China’s valve casting sector has seen particularly rapid development in recent years. Although it has faced various challenges along the way, overall, its development trend is one of stability and growth. It has also gradually become one of the industries with the fastest development in China’s domestic machinery sector. Valve casting forms the foundation of China’s foundry industry and drives the development of the entire sector, playing a significant role in promoting the growth of China’s national economy. According to statistics on industrialization abroad, the output value of valves equals the sum of the economic values of compressors, fans, and pumps, accounting for approximately 5% of the total output value of the machinery industry. At the same time, valves, as an important component of technical equipment, play a crucial role, especially in industries such as metallurgy, petrochemicals, chemicals, power generation, and urban pipeline drainage. In recent years, infrastructure investment in China has continued to grow, leading to significant improvements in the valve manufacturing industry. Nevertheless, the valve casting industry faces the same drawbacks as the development of China’s industrial machinery sector: a low level of development, low technical content in its products, a limited range of product types, unstable quality, and the absence of high-quality end products. They are at the forefront of the development of the valve casting industry. China’s valve manufacturing industry is still in a stage of development; it lacks core technologies, automated control systems, and a highly skilled management team, which means it has a long way to go compared to the valve manufacturing industries abroad. Against the backdrop of continuous development, why is there such a large gap between valve casting in China and that abroad? The reasons are: 1, a lack of talent in technological innovation. The most fundamental reason is **that the company does not make an effort to develop talent. 2. There is no spirit of breakthrough in terms of technology. 3. Gaps in quality management and equipment. 4. Differences in the product production process. Taken together, these four factors are causing the gap between China’s cast valves and those abroad to widen. I believe that in the future, our country’s valve industry will develop very rapidly
