Valves are products with low profit margins, and the market competition is very fierce. Regarding the distribution of the valve market, it is mainly based on the construction of engineering projects. The largest 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, globe valves and check valves; the power sector mainly uses high-temperature pressure gate valves, globe 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, globe valves, check valves; metallurgical industry mainly uses low-pressure large-diameter butterfly valves, oxygen shut-off valves and oxygen ball valves; urban construction departments mainly use low-pressure valves, such as urban tap water pipelines mainly use large-diameter gate valves, and building construction mainly uses mid-line For butterfly valves, metal-sealed butterfly valves are mainly used for urban heating; flat gate valves and ball valves are mainly used for oil pipelines; stainless steel ball valves are mainly used in the pharmaceutical industry; stainless steel ball valves are mainly used in the food industry. 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 with a certain scale in the market, most of which are located in Jiangsu, Zhejiang and Central Plains. Due to the relatively low requirements for product technology content, the competition is more intense.

Since the 1980s, my country began to organize key enterprises to introduce advanced technology and processing equipment such as the design and technology of similar products from abroad, so that my country’s valve manufacturing technology and product quality have been rapidly improved, and it has basically reached the level of foreign countries in the 1980s. At present, domestic key valve manufacturers 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, and some manufacturers’ products have reached the international advanced level. Although the overall level of the valve industry in the New Year has been greatly improved, the quality is not stable enough, such as running, leaking, dripping, and leakage often appear in domestic valves. In addition, there is still a certain gap between my country’s valve supporting capabilities and developed countries.

On the one hand, my country’s valve products are facing good development opportunities. With the transfer 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 corresponding changes in the field of equipment application. 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 transition from low-pressure iron gate valves used in the past to environmentally-friendly rubber plate valves, balance valves, metal seal butterfly valves, and centerline seal butterfly valves. The development of oil and gas transportation projects in the direction of pipelines 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, steam traps should be developed and developed towards subcritical and supercritical high parameters.

The construction of the power station is developing towards large-scale development, so large-caliber and high-pressure safety valves and pressure reducing valves are required, and fast opening and closing valves are also required. For 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 the valves required by an engineering project are all provided by a valve manufacturer.

But on the other hand, we have to take many problems in the valve market seriously. As my country’s valve market has basically formed a coexistence of state-owned, collective, joint venture, stock and individual private companies. In the fierce market competition, which requires steady development, companies are paying attention to the following issues: working hard to reduce production costs, focusing on improving product performance and efficiency; developing high-end high-tech products or producing single-piece small batches of non-standard products; passing International quality certification of valve products; valve products should develop in the direction of environmental protection and energy saving. However, it is inevitable that some unscrupulous manufacturers who seek profit as their purpose and do not hesitate to harm the interests of others are disrupting the normal valve product market development.
