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。
