1.工作可靠性


指电磁铁通电后能否可靠地换向，而断电后能否可靠地复位。电磁阀也只有在一定的流量和压力范围内才能正常工作。这个工作范围的极限称为换向界限。


2.压力损失


由于电磁阀的开口很小，故液流流过阀口时产生较大的压力损失。


3.内泄漏量


在各个不同的工作位置，在规定的工作压力下，从高压腔漏到低压腔的泄漏量为内泄漏量。过大的内泄漏量不仅会降低系统的效率，引起过热，而且还会影响执行机构的正常工作。


4.换向和复位时间


交流电磁阀的换向时间一般为0.03~0.05s，换向冲击较大;而直流电磁阀的换向时间为0.1~0.3s，换向冲击较小。通常复位时间比换向时间稍长。


5.换向频率


换向频率是在单位时间内阀所允许的换向次数。目前单电磁铁的电磁阀的换向频率一般为60次/min。
