介质特性

1)质气,液态或混合状态分别选用不同品种的电磁阀;

2)介质温度不同规格产品,否则线圈会烧掉,密封件老化,严重影响使用寿命;

3)介质粘度,通常在50cSt以下。若超过此值,通径大于15mm时,用多功能电磁阀;通径小于15mm时,用高粘度电磁阀。

4)介质清洁度不高时都应在电磁阀前配装反冲过滤阀,压力低时,可选用直动膜片式电磁阀;

5)介质若是定向流通,且不允许倒流,需用双向流通;

6)介质温度应选在电磁阀允许范围之内。

2、管道参数

1)根据介质流向要求及管道连接方式选择阀门通口及型号;

2)根据流量和阀门Kv值选定公称通径,也可选同管道内径;

3)工作压差:低工作压差在0.04Mpa以上是可选用间接先导式;低工作压差接近或小于零的必须选用直动式或分步直接式。

3、环境条件
