An Analysis of the Five Major Trends in the Development of the Valve Market

Thread Content

The largest users of valves are the petrochemical industry, power sector, metallurgical industry, chemical industry, and urban construction sector. The petrochemical industry primarily uses gate valves, globe valves, and check valves that comply with API standards ； The power sector primarily uses high-temperature gate valves, stop valves, check valves, and safety valves for power plants, as well as low-pressure butterfly valves and gate valves for some water supply and drainage applications ； The chemical industry primarily uses stainless steel gate valves, globe valves, and check valves ； The metallurgical industry primarily uses low-pressure, large-diameter butterfly valves, oxygen stop valves, and oxygen ball valves ； The urban construction sector primarily uses low-pressure valves, such as large-diameter gate valves used in urban water supply pipelines, centerline butterfly valves used in building construction, and metal-sealed butterfly valves used in urban heating systems ； Flat gate valves and ball valves are primarily used in oil pipelines ； The pharmaceutical industry primarily uses stainless steel ball valves ； The food industry primarily uses stainless steel ball valves and similar components. Due to changes in user demands, the market trends for valve products will also change accordingly. The main development trends in the coming period are as follows: 1. As oil exploration shifts to inland and offshore fields, and as the power industry develops from thermal power plants with capacities below 300,000 kilowatts to those with capacities above 300,000 kilowatts, as well as to hydroelectric and nuclear power plants, valve products must also adjust their performance and specifications in line with these changes in the areas where they are used ； 　　2. The urban construction sector generally uses a large number of low-pressure valves, and there is a trend toward more environmentally friendly and energy-efficient solutions. That is, low-pressure iron gate valves that were used in the past are being gradually replaced by environmentally friendly types such as diaphragm valves, balance valves, metal-sealed butterfly valves, and center-sealed butterfly valves. Oil and gas transmission projects are moving toward pipeline-based systems, which in turn requires a large number of flat gate valves and ball valves ； 　　3. The other aspect of energy development is energy conservation; therefore, from the perspective of saving energy, it is necessary to develop steam traps and move towards higher parameter levels such as subcritical and supercritical conditions ； 　　4. As power stations are becoming larger in scale, large-diameter and high-pressure safety valves and pressure relief valves are required, as well as valves that can be opened and closed quickly ； 　　5. To meet the needs of complete engineering projects, valve supply has evolved from single varieties to multiple varieties and specifications. There is an increasing trend for a valve manufacturer to supply all the valves required for a construction project.
