ASCO阿斯卡直动式电磁阀高温流体：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、美国ASCO阿斯卡直动式电磁阀流体状态：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、美国ASCO阿斯卡直动式电磁阀根据压力参数选择电磁阀的：原理和结构品种
1、美国ASCO阿斯卡直动式电磁阀公称压力：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、美国ASCO阿斯卡直动式电磁阀工作压力：如果工作压力低则必须选用直动或分步直动式原理；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。
designed for indoor use to protect personnel from
accidental contact with the equipment. P-Series
