along with the science unceasing development and the progress, the valve profession has gained a firm foothold in china. the pace of technological innovation is accelerated, further optimization of the product structure of the mechanical industry valve, so that the valve and actuator have better performance, oil price stability and the expansion of the use of natural gas make the investment in oil and natural gas increase, accelerate the valve pneumatic control valve in the market position.
in the first half of the year, the added value of all 13 sub-industries of china's valve industry increased by double digits, with engineering valves and heavy mining valves growing the fastest, data released by china valve industry federation showed wednesday. chemical industry and electrical industry, which account for a large proportion of the total, contributed nearly 59% to the growth of the whole industry. according to the data, the comprehensive economic benefit index of china's valve industry in the first half of the year was 169.55%, about 20 percentage points higher than the same period of last year, and the profit rate of main business income was 5.33, 0.49 percentage points higher than the same period of last year. the vice president of china valve industry federation said that the government's policy to revitalize the equipment manufacturing industry, strong market demand, industry investment capacity, and so on are the reasons for the high growth. data show that in the first half of the year, china's machinery industry exports generated foreign exchange of 65.2 billion us dollars, up 36.15 percent year-on-year, with a cumulative trade deficit of 1 billion us dollars, down about 2.6 billion us dollars year-on-year.
regulator related basic knowledge: also known as control valve, regulating valve which is divided into electric control valves, pneumatic film single-seat regulating valve, pneumatic control valve, pneumatic valve, cv3000 regulator, self-reliance type control valve, pneumatic sleeve valve, pneumatic cut-off valve, pneumatic diaphragm pressure sleeve valve, electric cut-off valve, small sleeve single-seat regulating valve, regulating valve accessories, fully functional light valve, electric actuator, single seat regulator, unbalanced cage control valve, power station special regulator, etc.
cai said that china's machinery industry valve trade growth has improved, the higher value-added of general trade exports accounted for an increase in the proportion of imports and exports of products gradually upgraded, automobiles, cnc machine tools, power generation equipment and other high value-added products have become highlights of export products. valve market in china has established a solid root.
