My Country's Valve Market Situation Analysis And Prospects

Since the 1980s, my country has begun to organize key enterprises to introduce advanced technologies and processing equipment such as design and technology of similar foreign valve products, which has rapidly improved my country's valve manufacturing technology and product quality. At present, domestic key valve production enterprises have been able to design and manufacture various valves in accordance with international standards such as ISO international standards, DIN German standards, AWWA American standards, etc., and the products of some manufacturers have reached the international advanced level. Although the overall level of the valve industry has been greatly improved in the past few years, the quality is not stable enough, and phenomena such as running, popping, dripping, and leaking often occur in domestic valves. In addition, there is still a certain gap between my country's valve supporting capabilities and developed countries.

Valve is a product with low profit margin, and the market competition is very fierce. As for the distribution of the valve market, it is mainly based on the construction of engineering projects. The users of valves are the petrochemical industry, power sector, metallurgical sector, chemical industry and urban construction sector. The petrochemical industry mainly uses API standard gate valves, stop valves and check valves; the power sector mainly uses high-temperature pressure gate valves, stop valves, check valves and safety valves for power stations and some low-pressure butterfly valves and gate valves for water supply and drainage valves; the chemical industry mainly uses Stainless steel gate valves, stop valves, and check valves; the metallurgical industry mainly uses low-pressure large-diameter butterfly valves, oxygen stop valves, and oxygen ball valves; urban construction departments mainly use low-pressure valves, such as urban water pipes mainly use large-diameter gate valves, and apartment construction mainly uses midline valves. Butterfly valves, urban heating mainly uses metal-sealed butterfly valves; 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. Valves are widely used in the water treatment industry, mainly low-pressure valve products, such as butterfly valves, gate valves, and check valves. It is understood that there are currently more than 2,000 valve companies of a certain scale on the market, most of which are located in Jiangsu, Zhejiang and the Central Plains. Since the technical content of the products is relatively low, competition is more intense.

On the one hand, my country's valve products are facing good development opportunities. With the shift of oil development to inland oil fields and offshore oil fields, and the development of the power industry from thermal power below 300,000 kilowatts to thermal power, hydropower and nuclear power above 300,000 kilowatts, valve products should also change their performance and performance according to changes in equipment application fields. parameter. Urban construction systems generally use a large number of low-pressure valves, and are developing towards environmental protection and energy saving. That is, the low-pressure iron gate valves used in the past are gradually turning to environmentally friendly rubber plate valves, balance valves, metal seal butterfly valves and centerline seal butterfly valves. Oil and gas transmission projects are developing in the direction of pipelines, which requires a large number of flat gate valves and ball valves. The other side of energy development is energy conservation. Therefore, from the perspective of energy conservation, steam traps must be developed and developed toward subcritical and supercritical high parameters.

The construction of power stations is developing towards large-scale development, so large-diameter and high-pressure safety valves and pressure reducing valves are required, as well as quick opening and closing valves. To meet the needs of complete sets of projects, the supply of valves has developed from a single variety to multiple varieties and specifications. There is an increasing trend that all valves required for an engineering project are provided by one valve manufacturer.
