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以上时直动式、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、DC24V
主要产品角座阀、电磁阀产品，气动元件，比例气动产品和用在微电脑通讯的系统，如阀岛、阀门连接系统、简单多线电缆的板快和连接器等等。 ASCO所有产品按照标准设计和生产，电磁阀产品可满足各种应用的需要，控制不同液态及气态流体，并提供广泛的选择：其介质可以是易燃、易爆或腐蚀性的；压力可达到150巴；温度可以从-50C到300C；口径从1/8英寸至6英寸，产品包括普通型、防爆型、手动复位、本安型、滑动式、长寿型、蒸汽/热水及气控阀。其出色的防爆性能广泛应用于石化、电厂等行业。同时，根据不同的产品也适用于其他行业如：环保和水处理以及医疗设备仪器等相关OEM配套等等。在气动控制产品方面，阿斯卡8215电磁阀/美国ASCO阿斯卡ASCO JOUCOMATIC能够设计出一些特别的气动元件以满足各种自动控制的需要。同时，为了适应电子化的要求，也提供比例气动产品和用在微电脑通讯的系统，如阀岛、阀门连接系统、简单多线电缆的板快和连接器等等。
ASCO长寿命电磁阀@ASCO防爆线圈，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。
