活塞式电磁阀的安装与维护
1、电磁阀一般是定向的，不可装反，通常在阀体上用“箭头”指出介质流动方向，安装时要依照“箭头”指示方向安装。
2、接管时应注意，密封材料不可使用过量，如螺纹连接时，接管螺纹应保持有效长度内，并在端部半螺纹距处用锉刀倒角，自端部起两牙处开始缠绕密封带，不然过量密封带或粘结将进入电磁阀内，而发生妨碍电磁阀正常动作的事故。
3、防爆电磁阀现场安装必须按照国家爆炸危险场所“电气安全规程”中有关规定进行。
4、非电气人员不得拆卸电磁阀电气部件。
5、安装活塞电磁阀前应仔细核对阅读产品使用说明书，检查产品是否完全符合使用要求，熟悉安装要点，做好准备工作。
6、核对品牌参数是否为所选用的参数，是否与使用说明书相符。
7、安装之前用管路的最高使用压力对管路充分冲洗，冲洗时间应在5分钟以上，把管路中的金属粉末、残留密封材料、焊接后的氧化皮等完全清除。
8、注意介质的清洁度，如果流通的介质中有杂质，电磁阀进口端前必须安装密度0.5um的过滤器。
9、电磁阀应水平安装，线圈在上。阀不宜装在低凹处，如装在容器的排出管道中，注意不可自容器底部引出，而应装在容器底部稍上的位置。
10、如果介质会起水击现象，要注意电磁阀的选用或采取相应的防范措施。
11、蒸汽用电磁阀入口前侧应安装流水阀，该处接管应倾斜，流水阀应装在低位，最好装多通反冲过滤器。
