China valve industry after decades of development, has made great progress, but there are also some problems can not be avoided. This paper describes the main problems in the valve market, the trend and the status quo and put forward some suggestions for the industry reference, exchange.
After decades of development, the valve industry has been able to provide for the user departments about twelve categories, more than 3 thousand types, more than 4 thousand specifications of products, high pressure valve performance parameters range from vacuum valve to 600Mpa, temperature from cryogenic temperature -196 degrees Celsius to 570 degrees celsius. The medium is water, steam, urea, ethylene, explosive and other media. Valve is a low margin products, market competition is very fierce. Valve in the water treatment industry, the use of large, mainly in low-pressure valve products, such as gate valve butterfly valve. It is understood that the market has a certain size of the valve more than 2000 enterprises, most located in Jiangsu and Zhejiang and the Central Plains area.
At present, the domestic valve production backbone enterprises have been able to ISO international standards, DIN German standard, AWWA American Standard and other international standards for the design and manufacture of various valves, some manufacturers of products 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 stable enough, such as run, run, drip, leakage phenomenon in the domestic valve often occurs. In addition, the supporting capacity of the valve is also compared with the developed countries there is still a certain gap. How to deal with the valve industry in the market competition, from the whole, China’s valve market prices are relatively stable, although a slight decline every year, but the magnitude is very small. Recently, Taiyuan, Tianjin, an inspection of the valve market and found that many companies for profit shoddy, serious disruption of the valve market.
Major problems in the valve market：
一、Some of the operators to buy the sitewithout valves, print well-known brand-name manufacturers and the certification of qualified valve causing serious harm to corporate reputation.
二、Renovation of the valve, part of the operator through the waste valve to re paint the second sale, to the quality of the project brings serious security risks.
The trend of valve field in china :
1、Construction is just like large-scale development, so the need for large diameter and high pressure safety valve and pressure relief valve, but also need to quickly open and close the valve。
2、Energy development is energy conservation, from the point of view of energy conservation to the development of steam water valve, and the development of subcritical and supercritical parameters.
3、City construction also transition to energy saving and environmental protection, before the general use of low-pressure valves, especially iron only low pressure valves, now to the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition, oil pipeline and gas pipeline project gradually developed more flat gate valve and ball valve.
4、According to the needs of the complete set of projects, the valve manufacturer should be developed to many varieties and specifications. A project needs to be able to make a valve manufacturer has become a trend.
China’s valve market has basically formed a state-owned, collective, joint ventures, shares and the coexistence of individual and private situation. If an enterprise wants to obtain the steady development in the fierce market competition, we can start from the following aspects.
1、Efforts to reduce production costs and focus on improving product performance and efficiency.
2、Non standard products of high-tech product development and quality production of single or small groups of.
3、International quality certification of valve products.
4、Valve products should be environmentally friendly, energy-saving direction.
5、On the basis of the original valve varieties, expand the production of other varieties and models of the valve.
