1力士乐电磁阀电磁阀和全不锈钢;对于强腐蚀的介 质必须选用隔离膜片式。中性介质,也宜选用铜合金为阀壳材料的电磁阀,否则,阀壳中常有锈屑脱落,尤其是动作不频繁的场合。氨用阀则不能采用铜材。
2、爆炸性环境:必须选用相应防爆等级产品,露天安装或粉尘多场合应选用防水,防尘品种。
3、电磁阀公称压力应超过管内zui高工作压力。
适用性:
1、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,严重影响寿命命;
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。
