The latest statistics released by the Korea Machine Tool Industry Association (KOMMA) show that from January to July 2010, South Korea's cumulative production of machine tools totaled 1,522.65 billion won (approximately 8.707 billion renminbi), an increase of 62.38% over the same period of last year. In July, the output value of Korean machine tools was 249.638 billion won (about 1.428 billion renminbi), which was an increase of 1.57% from the previous month and a significant increase of 113.04% year-on-year. From January to July this year, South Korea's cumulative new machine tool orders reached 2,132.24 billion won (about 11.509 billion yuan), an increase of 115.33%. In the month of July, South Korea's new machine tool orders totaled 244.715 billion won (approximately 1.399 billion yuan), a decrease of 18.35% compared with the previous month and a year-on-year increase of 103.18%. KOMMA said that in the last two months, new orders for machine tools in South Korea have significantly declined, and may show highs and lows in the whole year. In terms of imports, from January to July 2010, South Korea's cumulative value of imported machine tools was US$757 million, a year-on-year increase of 25.54%. In July, South Korea imported machine tools worth 125 million U.S. dollars, an increase of 6.18% from the previous quarter and an increase of 17.92% year-on-year. In terms of exports, from January to July this year, South Korea exported machine tools totaling US$893 million, a year-on-year increase of 30.94%. Among them, in July, exports of machine tools 169 million US dollars, an increase of 5.71%, an increase of 92.05%. KOMMA told reporters that China is South Korea's largest machine tool export market, South Korea's machine tool manufacturers plan to develop products suitable for the needs of Chinese users, thereby expanding the market share in China. There are five general body styles of Ball Valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve-especially the casing that contains the ball itself-are manufactured and assembled. The valve operation is the same in each case.

In addition, there are different styles related to the bore of the ball mechanism itself.
Ball Valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
South Korea's January-July machine tool trend is good to expand the Chinese market
