德國萊克LIK品牌：進(jìn)口低溫電磁閥應(yīng)用范圍、它廣泛應(yīng)用于航天、船舶重工、化工、冷凍設(shè)備、食品醫(yī)設(shè)備等制冷管道系統(tǒng)中。
產(chǎn)品特點(diǎn)：
閥芯均為不銹鋼活塞式，活塞環(huán)用特殊耐低溫、耐磨材料制作；活塞與金屬閥腔不產(chǎn)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(dāng)線圈通電時，先導(dǎo)閥芯吸合，先導(dǎo)孔打開，閥上腔卸壓，活塞靠下腔介質(zhì)壓力推動，電磁閥打開；當(dāng)線圈斷電時，先導(dǎo)閥芯靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)閉。
