The Future Development Trend of Global Valve

　　With the development of technology of large complete, a series of new equipment are appeard. And the features of the development of new valve-related equipment are large, high-parameterization, high-performance automation and complete set , the control mode is corresponding with the complete sets of equipment. The past 20 years, the valve control mode is also great development. Apart from manual, mechanical, electrical, pneumatic, hydraulic transmission; the electro-hydraulic connections, gas-liquid connections, automatic control valves varieties are growing and have further development trend.
    Such as oil refining equipment. The largest oil refinery, 36.4 million tons / year (the Caribbean Virgin Islands), 30 million tons / year (Venezuela). At present, oil refinery with 20 million tons / year is more than nearly 30; the capacity of the largest oil refinery devices reached to 24 million tons / year, catalytic cracking unit to reach 8.24 million tons / year, hydrocracking unit to reach 3.2 million tons / years. Large units, are forcing the valve grown, and the control automation has also begun to develop in the direction.
    In recent years, long-distance pipeline developed rapid with the main reasons: First, low cost, only about rail transport 1 / 3; 2 it is buried in the ground, not easy to destroy; Third, pipeline construction is fast, low investment. Therefore, the long pipeline valves demand is increasing in recent years.
    In these valve supporting with complete sets of equipment, the valve diameter of the largest flat panel reached 1620mm, 2000mm; largest ball diameter is 3050mm, not including the drive valve weight is 184 tons; the biggest valve gate diameter for water is 2750mm, the pressure to 9MPa.
    The economic effects of large scale equipment: 1、improve the production efficiency, 2、reduce investment in infrastructure, 3、reduce the consumption of raw materials and fuel. Comparing oil refining equipment of an annual capacity 5,000,000 tons to 100 tons, the investment of production capacity per ton reduce by 50%.  Between a 600 ton / year refinery and two 3 million t / year refinery, the investment is only about 69% of the latter, 53% of steel consumption, an area of 54%, 75% of production costs, but the labor productivity has increased to 170%.
