the demand for industrial valves will expand from its present level of just under $ billionyr to over $ billionyr by the main driver will be the energy needs of the developing countriesenergy butterfly valves
already accounts for overpercent of valve demandpower, refining, and oil and gas are all going to expand at a rate faster than average gdp during the next two decadesthese are the latest forecasts in industrial valves: world markets, a continually updated online report of more thanpages published by the mcilvaine company
the market for combined cycle gas turbines plug valves
will grow at a rate faster than coal but represents a smaller market for valvesvalve expenditures for oil and gas production will increase as subsea and other challenging environments are increasing the locations for new extractionrefining represents the third largest single marketthe trend toward utilization of less desirable fuel stock will result in continuing upgrading and increased valve requirement in this sector
china will be the largest purchasing country of valves for new plants (not replacement) during the periodmuch of the supply will be availablefilter
from domestic sourcesneway, the largest chinese supplier, has nuclear stamps and can deliver high performance valvesa number of international companies are continuing to build their chinese presence for two basic reasonsone is to gain market share in china and the other is to provide a base to export to the rest of asia and other regions of the world
in general the valve industry will become more international and consolidated in the next two decadespresently there are only three companies with over $ billion in valve salesthey presently capturepercent of the marketmore than , companies participate in the valve market around the worldover the next two decades this number will shrink as global players expand their role

译文年工业阀门市场
对工业阀门的需求将扩大其仅低于亿年的水平，以超过亿美元年到年。主要驱动力将是能源的发展中国家的需要。能源已经占了阀门的需求增长。电力，炼油，石油和天然气都将速度快于国内生产总值平均扩大，在未来二十年。这些都是工业阀门的最新预测全球市场，一个不断更新由mcilvaine公司公布的多页的在线报告
燃煤发电所mcilvaine预计增加的万兆瓦，到年达到万兆瓦，然后缓慢，,兆瓦的-期间增加了。这将导致万总装机在年煤炭基地。阀门的需求将大幅增加，由于寿命延长的努力煤燃煤电厂在美国这将进一步增加的要求安装污染控制设备，甚至是二氧化碳捕捉系统。
气候变化法规可能会影响长期市场，但不会有太大影响，到年之前。原因之一是可再生技术将在年之前不会捕获巨大的市场份额。第二个原因是，水电，生物能和地热能需要大量的阀门的投资。在太阳能领域的大型太阳能发电厂蒸汽比使用燃气联合循环更阀发电厂。第三个原因是，它需要更多的可再生能源的发电量相当于电力由于间歇操作。第四个原因是，在纤维素乙醇交换机将需要大量阀门投资。第五个原因是，在碳捕捉和封存项目阀的使用。
电子行业将继续波动，但在国内生产总值超过平均增长率。半导体工厂需要大量化学品的腐蚀阀门的关键数字，芯片洗，超纯水系统及其他应用。
中国将成为对（不更换期间）新电厂阀门的最大购买国。供给大部分将可从国内来源。新时代，中国最大的供应商，拥有核邮票，可提供高性能的阀门。阿一些国际公司正继续建立两个基本原因的中国的存在。其一是在中国获得更多的市场份额，另一个是提供一个基地，出口到亚洲和世界其它地区。
一般来说，阀门行业将会变得更加国际化，在未来年巩固。目前只有三个超过亿美元的阀门销售公司。他们目前捕获的市场份额。 ,多家企业参加世界各地的阀门市场。在未来年这一数字将缩小全球领导厂商扩展其作用。
