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

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。
