  The largest users of valves are the petrochemical industry, power sector, metallurgical sector, chemical industry, and urban construction sector. The petrochemical industry mainly adopts API standard gate valves, globe valves, and check valves; The power sector mainly uses high-temperature pressure gate valves, globe valves, check valves, safety valves for power stations, as well as low-pressure butterfly valves and gate valves for some water supply and drainage valves; The chemical industry mainly uses stainless steel gate valves, globe valves, and check valves; The metallurgical industry mainly uses low-pressure large-diameter butterfly valves, oxygen globe valves, and oxygen ball valves; The urban construction department mainly uses low-pressure valves, such as large-diameter gate valves for urban water pipelines, centerline butterfly valves for building construction, and metal sealed butterfly valves for urban heating; Oil pipelines mainly use flat gate valves and ball valves; The pharmaceutical industry mainly uses stainless steel ball valves; The food industry mainly uses stainless steel ball valves, etc. Due to changes in user demand, the market trend of valve products will also undergo corresponding changes.
  With the shift of oil development to inland and offshore oil fields, and the development of the power industry from thermal power below 300000 kilowatts to thermal power, hydropower, and nuclear power above 300000 kilowatts, valve products should also change their performance and  parameters accordingly according to changes in equipment application fields;
  The urban construction system generally adopts a large number of low-pressure valves and is developing towards environmentally friendly and energy-saving types, gradually transitioning from the previously used low-pressure iron gate valves to environmentally friendly rubber plate valves, balance valves, metal sealed butterfly valves, and centerline sealed butterfly valves. Oil and gas transmission projects are developing towards pipeline oriented direction, which requires a large number of flat gate valves and ball valves;
  The other side of energy development is energy conservation, so from the perspective of energy conservation, we need to develop steam trap valves and move towards subcritical and supercritical high parameter development;
  The construction of power stations is moving towards large-scale development, so large-diameter and high-pressure safety valves and pressure reducing valves are needed, as well as quick opening and closing valves;
  In response to the needs of complete engineering projects, valve supply has evolved from a single variety to multiple varieties and specifications. The trend of one valve manufacturer providing all the valves required for an engineering project is increasing.
