美国ASCO电磁阀选型依据：
　　一、根据管道参数选择电磁阀的：通径规格（即DN）、接口方式
　　　　1、按照现场管道内径尺寸或流量要求来确定通径（DN）尺寸。
　　　　2、接口方式，一般>DN50要选择法兰接口，≤DN50则可根据用户需要自由选择。
　　二、根据流体参数选择电磁阀的：材质、温度组
　　　　1、腐蚀性流体：宜选用耐腐蚀电磁阀和全不锈钢；食用超净流体：宜选用食品级不锈钢材质电磁阀。
　　　　2、高温流体：要选择采用耐高温的电工材料和密封材料制造的电磁阀，而且要选择活塞式结构类型的。
　　　　3、流体状态：大至有气态，液态或混合状态，特别是口径大于DN25订货时一定要区分开来。
　　　　4、流体粘度：通常在50cSt以下可任意选择，若超过此值，则要选用高粘度电磁阀。
　　三、根据压力参数选择电磁阀的：原理和结构品种
　　　　1、公称压力：这个参数与其它通用阀门的含义是一样的，是根据管道公称压力来定。
　　　　2、工作压力：如果工作压力低则必须选用直动或分步直动式原理；zui低工作压差在0.04Mpa以时直动式、分步直动式、先导式均可选用。
　　　四、电气选择：电压规格应尽量优先选用AC220V、DC24较为方便。
　　五、根据持续工作时间长短来选择：常闭、常开、或可持续通电
　　　　1、当电磁阀需要长时间开启，并且持续的时间多余关闭的时间应选用常开型。
　　　　2、要是开启的时间短或开和关的时间不多时，则选常闭型。
　　　　3、但是有些用于安全保护的工况，如炉、窑火焰监测，则不能选常开的，应选可*通电型。
　　六、根据环境要求选择辅助功能：防爆、止回、手动、防水雾、水淋、潜水
一）、美国ASCO电磁阀原理
  原理：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧力把关闭件压在阀座上，阀门关闭。
  特点：在真空、负压、零压时能正常工作，但一般通径不超过25mm。
  （二）、asco分步直动式电磁阀
  原理：它是一种直动和先导式相结合的原理，当入口与出口压差≤0.05Mpa，通电时，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。
  当入口与出口压差>0.05Mpa，通电时，电磁力先打开先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀和主阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。
  特点：在零压差或真空、高压时亦能可靠工作，但功率较大，要求竖直安装。
  （三）、美国ASCO电磁阀原理2
  原理：通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，推动关闭件向上移动，阀门打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速进入上腔室在关阀件周围形成下低上高的压差，推动关闭件向下移动，关闭阀门。
  特点：流体压力范围上限很高，但必须满足流体压差条件

美国ASCO电磁阀选型依据
asco电磁阀动开关公司（ASCO）zui初是生产升降机，压缩机和发电机控制装置的公司，1910年成为首开发制造一种新的电动操作控制装置，也就是*的电磁阀。ASCO继续在这些产品领域积极地开发 ，如今制造的产品广泛用于空气、燃气、液体等流体控制和电力控制领域。ASCO生产3000多种型号的标准电磁阀和超过20，000多种特殊型号产品。　　ASCO® RED-HAT® –电磁阀主要用于精确控制， 在工商业应用中控制空气、 燃气、水、轻油、蒸汽等几乎所有流体和气态物质。为了满足新设备不断增长的需要，一些新的相关产品也被开发出来，比如气动操作阀，手动复位阀，和智能阀等。美国ASCO电磁阀原理2同时生产制造多种阀，当一种标准产品不能*适用新的需要时，这些阀就可以满足原始设备制造商市场的个性化需求。参照具体 产品介绍可获得更详细资料。
　　1920年，ASCO又有了一次巨大突破，为紧急电源控制开发出*种自动转换开关。这一产品可以感应到停电状况，将关键电力负荷从断电的正常电源中转移到紧急备用电源。如今，ASCO的电源开关组成的产品用于控制备用电源现场发电机，包括关闭转换调节开关，同时发电并降低峰值负荷， 储备电力和能源的管理，也用于照明控制和其他电力应用。
　　70年代中期， ASCO引进了*的压力和温度开关系列，用以满足多变的工业应用要求。ASCO 三定点压力和温度开关能感应各种流体的压力和温度。在操作中，它们会发出一个警报信号或者关闭系统。在其他操作中，它们能控制设备的开启顺序，比如压缩机或者电磁阀。
　　1985年，ASCO和JOUCOMATIC合并组建了ASCO/JOUCOMATIC。JOUCOMATIC是法国领的气动元件制造商。这些产品包括气控先导电磁阀，换向控制阀，比例阀和过滤、调节、润滑装置等。
　　此外，ASCO以几种不同的品牌来销售电磁阀产品。这些包括控制易燃介质的ASCO/GENERAL CONTROLS®，医疗市场的ASCO SCIENTIFIC®，较普通场所应用的SIRAI ®。所有这些产品都具有如您所期望的领于控制阀工业的高精品质和可靠性能。
电磁阀选型首先应该依次遵循安全性，可靠性，适用性，经济性四大原则，其次是根据六个方面的现场工况（即管道参数、流体参数、压力参数、电气参数、动作方式、特殊要求进行选择）。
