| 德国莱克LIK品牌：应用范围、它广泛应用于航天、船舶重工、化工、冷冻设备、食品医设备等制冷管道系统中。 产品特点：
阀芯均为不锈钢活塞式，活塞环用特殊耐低温、耐磨材料制作；活塞与金属阀腔不产生直接摩擦，阀体安装方向无限制；特制线圈，不易烧毁；长时间停止动作重新启动，作同样灵敏。 Applications:
It is widely used in aerospace, shipbuilding Heavy Industry, chemical, refrigeration equipment, Medical equipment, food refrigeration piping systems. Features:
Spool is stainless steel piston, piston ring with a special low temperature resistant, wear-resistant material; the piston and the metal does not produce direct friction valve chamber, valve mounting direction unlimited; special coil, not easy to burn; a long time to stop action to re-start, for the same sensitivity 主要技术参数： 产品规格： | DN0.5～DN100 | 阀体材质： | 不锈钢 | 适用介质： | 液氮、气、油、蒸汽、腐蚀流体等 | 温度范围： | -200～+150℃ | 介质粘度： | 小于50C St(大于时需定制） | 防护性能： | 防潮、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： | DC24～127V; 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。
常开：当线圈通电时，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。当线圈断电时，先导阀芯靠弹簧复位，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。 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, medium pressure piston push the lower chamber, the electromagnetic valve is opened.
