Domestic valve market trend analysis and prospect

Since the 80s, China began to organize backbone enterprise introducing foreign valve of the same products design, technology and other advanced technology and processing equipment, make our country valve manufacturing technology and product quality has rapidly improving. At present, the domestic backbone enterprise already can valve production according to ISO international standard, the German DIN standards, such as the international standard AWWA standard design and manufacture all kinds of valve, in part, the product of manufacturer of reached the international most advanced level. Although the valve industry over the past few years the overall level is distinctly improved, but on quality stable enough, such as running, running, drop, leakage phenomenon in domestic often appears in the valve. In addition, China valve supporting ability also compared with developed countries, there are still some difference.

The valve Hydrant Valve is low profit products, market competition is fierce. Is the distribution of the main valve market, is based on the construction of the project, the valve is biggest users petrochemical industry, electric power, metallurgy, chemical engineering department department of industry and urban construction department. The petrochemical industry main application API standard gate, globe valve and check valve; Power department mainly USES the power station with high temperature pressure gate, globe valve, check valve and relief valve and part of the water supply and drainage of low pressure valves, gate valves butterfly valve; Chemical industry mainly adopts stainless steel gate valves, globe valves, check valves; Metallurgy industry mainly use the low voltage large-size butterfly valves, globe valves and oxygen ball valve oxygen; The city construction department mainly use the low pressure valves, such as urban tap water pipe main with heavy-caliber gate, building containing the construction mainly USES the midline butterfly valve, city heating mainly USES the metal sealing butterfly valve; Oil pipelines mainly USES the flat valve and ball valve; The pharmaceutical industry mainly adopts stainless steel ball valve; The food industry mainly adopts stainless steel ball valve, etc. The valve in water treatment industry, mainly to use bigger low-pressure valve products, such as butterfly valves, gate valves, check valves. According to information, on the market at present of a certain size valve like Hydrant Valve enterprise have more than 2000, most distribution in jiangsu and zhejiang zhongyuan area and. Because the product technology content requirements relatively low, therefore, more competitive.

On the one hand, China Valve products like face with good chances. As the oil development to the mainland and the transfer of oil offshore oil field, and the electric power industry by 300000 kw to 300000 kw thermal power of the above and hydropower and thermal power of nuclear power development, valve products also shall be based on equipment application field changes corresponding change their properties and the parameters. Urban construction system of general use of low pressure valves, and environmental protection and development to energy-saving, namely the low voltage iron gate valves used in the past gradually turned to the environmental protection plastic board valve, balancing valve, metal sealing butterfly valve sealing butterfly valve and Central Line transition. Oil and gas engineering to GuanDaoHua direction, it need a lot of flat valve and ball valves. Energy development is on the other side of the energy saving, so from energy saving look, to develop the steam trap, and to the critical and supercritical parameters of the high development.

The construction of the power station to the large-scale development, so need large diameter and high pressure relief valve and relief valve, also need quick opening and closing of the valve. Complete the need of project, by a single varieties valve supply to many varieties and specifications development. A project required by a valve, valve manufacturer of all provide more and more trend.
