The valve is one of the key equipment of the fluid control system at present, including the valve of the main application fields of oil and gas, electric power, chemical industry, tap water and sewage treatment, papermaking, metallurgy, petroleum and natural gas industries; the energy and chemical industry, electric power is the most important application field of valve. According to the forecast market forecast of McIlvaine Corporation, demand for industrial valves will reach $100 billion by 2030, the demand for energy in developing countries is the main factor to promote the development of demand; is expected in 2015 to 2017, Chinese industrial valve industry market size growth rate will stabilize at around 7%, far higher than the growth of the global industrial valve industry speed.
China’s valve industry originated in the last century in 60s, in the last century before 80s only the production of more than and 600 varieties, more than 2 thousand and 700 specifications of valve products, lack the ability of design and production of high parameters, high technology content of the valve. In order to meet the industrial and agricultural production of China’s rapid development of high parameter and high technology content of the valve needs, from the last century at the beginning of 80s, China began to adopt independent development and introduction of technology combined with the development technology of the valve part of the valve backbone enterprises to increase R & D efforts, the introduction of technology climax valve. At present, our country has been able to produce gate valve, globe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, relief valve, drain valve and other valves, a total of 12 categories, more than 3 thousand types, more than 40 thousand specifications of valve products.
According to ValveWorld statistics, the global industrial valve market demand, including drilling, transportation and petrochemical, oil and gas sector accounted for the highest, reaching 37.40%, followed by the energy and chemical industry demand, market demand accounted for 21.30% and 11.50% of the global industrial valves, the top three in the field of market demand total demand 70.20% of the total market. While in the field of application of domestic industrial valves in chemical industry, energy, electricity and oil and gas industry is the main sales market, the valve market demand respectively of the total domestic demand valve market industry 25.70%, 20.10% and 14.70%, together accounted for 60.50% of the total market demand.
From the market demand, water conservancy and hydropower, nuclear power, oil and gas industry will continue to maintain strong demand for the future trend of the valve, mainly reflected in the following areas:
In the field of water conservancy and hydropower, the State Council issued the “energy development strategy action plan (2014-2020)” pointed out: by 2020, and strive to reach 350 million kilowatts of conventional hydropower installed. Hydropower installed capacity growth will bring a lot of demand for the valve, water conservancy and hydropower investment continued to stimulate the growth of water industry will stimulate the valve.
