- 进口水用电磁阀德国莱克（LIK）品牌：进口水用电磁阀应用范围：
它广泛应用在航天、船舶重工、石油化工、工业炉窑、锅炉、给排水、采暖空调、消防设备、干燥设备、食品医疗设备、清洗设备、景观喷灌、水厂等管道系统中。p>
进口水用电磁阀产品特点：
先导式结构，阀芯均为不锈钢活塞，活塞环不会被介质中的杂质卡死，动密封性能高,寿命长；活塞与金属阀腔不产生直接摩擦，阀体安装方向无限制；专制线圈，不易烧毁；长时间停止动作重新启动，动作同样灵敏；泄漏量零；使用寿命长达100万次以上。
主要技术参数：

水、气、油、蒸汽、燃气、腐蚀流体等
温度范围：
-200～+300℃
介质粘度：
小于50C St(大于时需定制）
防护性能：
防水、防爆（Exd IICT5)、防腐
接线方式：
接线座式；引线式、插头式
控制方式：
常开、常闭
电源电压：
DC12～127V; AC36～380V
连接方式：
内螺纹、法兰（外螺纹和特殊接口可定做或加转接头）
工作原理：
常闭：当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开；当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。

How it works:
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed.
Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote the solenoid valve open.
