With the "15" end of the valve market and industry of the various developments and changes in shares and the private sector to increase brass angle valve , the production level of the valve, valve output growth. Valve market sets the rate of complete sets of ability levels and greatly enhanced. Currently, the status of the valve market, the "Eleventh Five-Year" period the demand for petrochemical valves is forecast as follows: "Eleventh Five-Year" period, the petrochemical ethylene cracker in the field of high temperature gas valve is 800,000 tons ethylene plant cracking furnace must export pipeline valves, valves for such enterprises should consider the development of cracked gas valve. In addition, the large-diameter high-pressure ball valve,brass ball valve of large diameter pipelines, liquefied natural gas with a greater demand for low-temperature valve. Common equipment is expected throughout the valve industry "Eleventh Five-Year" period, the demand for 34.5 billion. In addition, according to the needs of China's national economic development, the focus of the valve for the development of thermal power, nuclear power, hydropower, large-scale petro-chemical, oil and natural gas gathering and transportation pipelines, coal liquefaction and metallurgical construction of major projects such as the valve supporting the development of new products. More than in the development of new products at the same time, should pay attention to the promotion of new technology applications, such as the development of nuclear power stations and high-temperature high-voltage brass check valve structure using welding applications forging vacuum electron beam welding process and the new shear extrusion technology; the development of large long-distance pipeline the overall application of the overall caliber ball valve welding technology.
