產品特點：
閥芯均為不銹鋼活塞式，活塞環用特殊耐低溫、耐磨材料制作；活塞與金屬閥腔不產生直接摩擦，閥體安裝方向無限制；特制線圈，不易燒毀；長時間停止動作重新啟動，作同樣靈敏。
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：
常閉：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開；當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。
