德莱赛公司（Dresser） 执行机构RCS Electric Actuators

德莱赛公司（Dresser）是目前 的专业工业用阀门制造商之一，产品主要供应给全球能源行业，用于能源的探勘、开采、运输、提炼和发电等。产品包括各种调节阀（Controlp Valves），安全阀（Safety Valves），安全泄放阀（Safety Relief Valves）以及关断阀（On/Off Valves）。主要品牌计有GROVE, TK,MASONEILAN, CONSOLIDATED, 等。德莱赛总部位于美国的达拉斯，在全球有28家制造厂，产品遍及120个国家和地区。公司2003年销售额达15亿美元。在中国已设有北京代表处负责对中国的销售业务。德莱赛于04年5月在苏州工业园区投资成立了美商独资的德莱赛机械（苏州）有限公司，即将开始营运。

Masoneilan公司创立于1882年， 早的名称是梅森公司，成立后很快就因在蒸汽、气体和液体调节设备领域的不断创新发明而确立了其在控制领域的地位与名声，1931年Masoneilan收购了位于洛衫机的尼兰公司，这项收购诞生了梅森尼兰公司，1985年美国德莱塞（Dresser）工业公司收购了梅森尼兰。

在120多年的历史里， Masoneilan创下了控制阀领域的多项一：

◆ zui先开发了大大简化阀门口径的设计概念
◆ zui先开发了控制阀顶部导向和底部导向技术
◆zui先研制出通用控制阀（Camflex）以及zui先发明了用于控制阀口径计算和设计过程中可能预测其噪音的方法。门

现在Masoneilan公司仍然继续不断的设计和制造按用户特定要求而生产的产品，以满足zui严峻的要求。诸如高压降煤浆、喷气发动机测试台、液态氢节流和严重的空蚀测试的应用等等。

通用电气公司已斥资30亿美元成功收购了Dresser公司。Dresser的总部位于美国德克萨斯州Addison市，在全球共有6300名员工。该公司主要生产阀门、执行器、开关、调节器、管件以及其它各种用于压缩、流体技术、计量以及配送设施的产品，Dresser的六成收入来自北美洲之外，它的业务将被合并入通用电气旗下的电力及水处理事业部以及工程服务事业部。这次收购将使通用日立核能公司(GE Hitachi)扩展其在核反应堆零部件方面的供货能力和范围。合并后的Dresser近来已获得了一份蒸汽安全阀供应合同，供货对象是将于2012年至2014年在佐治亚州和南卡罗林纳州建造的四座西屋电气公司(Westinghouse)的核反应堆。
