Valve capacity in China compared with foreign countries there is a gap
Valves are low-margin product, market competition is fierce. Valve market distribution is mainly based on project construction, petrochemical industry is the biggest user of valves, power sector, metallurgy, chemical industry and urban construction sectors. Petrochemical industry main application API standard of gate, and as valve and check back valve; power sector main used power station with high temperature pressure gate, and as valve, and check back valve and safety valve and the part to drainage valve of low voltage butterfly valve, and gate; chemical industry main used stainless steel gate, and as valve, and check back valve; metallurgical industry main used low voltage big caliber butterfly valve, and oxygen as valve and oxygen ball valve; city construction sector main used low voltage valve, as City tap water pipeline main used big caliber gate, floor Yu construction main used Middle butterfly valve, Urban heating using metal sealing butterfly valve pipeline using flat plate gate valves and ball valves pharmaceutical industry mainly uses stainless steel ball valve food industry mainly uses stainless steel ball valve and so on. Large amount of valves used in water treatment, mainly in the low pressure valve products, such as butterfly valves, gate valves, check valves. It is understood that currently on the market with a certain scale valve company has more than 2000 companies mostly in Jiangsu and Zhejiang provinces and the central area. Because of the technological content of products are relatively low and, therefore, more competitive.
On one hand, valves products in China are facing good opportunities for development. With transfer of the oil fields and offshore oil development to the Mainland, and 300,000-kilowatt all the electric power industry following coal-fired power plants to more than 300,000-kilowatt of thermal power and hydropower and nuclear power developments, valves should also change according to the application areas change their properties and parameters. Urban construction system consists of low pressure valve and to the development of environment-friendly and energy-efficient, which used low-voltage iron gate towards environmentally-friendly plastic valves, balancing valve, metal seated butterfly valve and centerline butterfly valve transition. Oil, gas project to develop in the direction of pipes, which requires a lot of flat gate valves and ball valves. Energy is on the other side of the development of energy-efficient, so from the perspective of energy conservation, the development of steam traps and subcritical and supercritical parameters of high development.
