Valves are products with low profit margins and the market is highly competitive. The distribution of the valve market is mainly based on the construction of the project. The largest users of the valve are the petrochemical industry, the power sector, the metallurgy sector, the chemical industry and the urban construction sector. The petrochemical industry mainly uses gate valves, globe valves and check valves of API standards; the power sector mainly adopts low-pressure butterfly valves and gate valves for power station high-temperature pressure gate valves, globe valves, check valves, and safety valves and some of the water supply and drainage valves; the chemical industry mainly adopts them. Stainless steel gate valve, globe valve and check valve; the metallurgical industry mainly uses low-pressure large-diameter butterfly valve, oxygen globe valve and oxygen ball valve; the urban construction department mainly adopts low-pressure valves, such as urban tap water pipelines mainly adopt large-diameter gate valves, and Louyu construction adopts the middle line. The butterfly valve, the city heating mainly uses the metal seal butterfly valve; The oil pipeline mainly uses the flat gate valve and the ball valve; The pharmaceutical industry mainly uses the stainless steel ball valve; The food industry mainly uses the stainless steel ball valve and so on. The valve is used in a large amount in the water treatment industry, mainly in low pressure valve products such as butterfly valves, gate valves, and check valves. It is understood that there are more than 2,000 valve companies with a certain scale on the market, most of which are located in Jiangsu, Zhejiang and Central Plains. Due to the relatively low technical content of products, the competition is even fiercer.
Since the 1980s, China has begun to organize key enterprises to introduce advanced technologies and processing equipment such as the design and craftsmanship of similar foreign products, which has enabled China’s valve manufacturing technology and product quality to rapidly improve, and has basically reached the level of foreign 80’s. At present, the domestic valve production backbone enterprises have been able to design and manufacture various valves in accordance with international standards such as ISO International Standard, DIN German Standard, and AWWA American Standard. Some manufacturers' products have reached the international advanced level. Although the overall level of the New Year's valve industry has been greatly improved, but the quality is not yet stable, such as run, run, drip, leakage phenomenon often occurs in domestic valves. In addition, there is still a certain gap between China's valve supporting capabilities and developed countries.
On the one hand, China's valve products are facing a good opportunity for development. With the shift from oil development to oil fields in the interior and offshore oil fields, and the development of thermal power and hydropower and nuclear power from 300,000 kilowatts to less than 300,000 kilowatts in the power industry, valve products should also change their performance in response to changes in equipment applications. 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 have gradually shifted to environmental-friendly rubber sheet valves, balancing valves, metal sealing butterfly valves and midline sealing butterfly valves. The development of oil and gas transmission 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. Therefore, from the aspect of energy conservation, we need to develop steam traps and develop them to subcritical and supercritical high parameters.
The construction of the power station has grown to large scale. Therefore, large-diameter and high-pressure safety valves and pressure reducing valves are required, and valves must be opened and closed quickly. The needs of complete sets of projects, valve supply from a single species to more varieties and more specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.
On the other hand, we have to take seriously many issues in the valve market. As China's valve market has basically formed a state-owned, collective, joint ventures, shares and individual private coexist. In the fierce market competition, steady development is required. Enterprises are paying attention to the following issues: working hard to reduce production costs, focusing on improving product performance and efficiency; developing high-tech products of high quality or producing small batches of non-standard products; Valve product international quality certification; valve products should be environmentally friendly, energy-saving direction. However, inevitably, some unscrupulous manufacturers who aim at making profits and do not hesitate to harm other people's interests will inevitably disrupt the normal development of the valve product market.
In general, the price of China's valve market is relatively stable. Although there is a slight increase and decrease every year, the range is very small. From the North China valve market, it has been discovered that many companies have shoddy for profit, seriously disrupting the valve market. The main problems in the valve market are: First, some operators purchase valves with no factory name, print well-known manufacturers' brand names and certifications, and cause serious damage to the reputation of qualified valve companies. Second, refurbishment of the valve, some operators re-painted the second time after the waste valve re-painted, giving the project quality a serious security risk.
Through the analysis of the valve market is not difficult to find, China's valve product market has a good development prospects, but must be through the standardization of market order and strict management, eliminate vicious competition, here calls the conscience of the industry and the government's quality supervision.
