德國萊克LIK品牌：進口高溫電磁閥應(yīng)用范圍：它廣泛應(yīng)用于船舶重工、測試設(shè)備、加熱設(shè)備、液壓設(shè)備等，工作溫度在550℃以上的導(dǎo)熱系統(tǒng)中。

產(chǎn)品特點：
閥芯均為不銹活塞式，活塞環(huán)用特殊耐溫、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，并采用散熱的結(jié)構(gòu)方式，因此不易燒毀；長時間停止動作重新啟動，動作同樣靈敏；最低啟動壓力0.2MPa。

Applications:
It is widely used in shipbuilding Heavy Industry, test equipment, heating equipment, hydraulic equipment, the working temperature above 300 ℃ thermal systems.

Features:
Are stainless steel piston valve, piston ring with a special temperature, wear-resistant material; piston valve chamber with the metal does not have a direct friction, the valve mounting direction unlimited; special coil structure and way of using heat, it is not easy burned; long time to restart the stopped action, action as sensitive; minimum starting pressure 0.2MPa.

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，閥關(guān)閉。
常開：當(dāng)線圈通電時，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。當(dāng)線圈斷電時，先導(dǎo)閥芯靠彈簧復(fù)位，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。

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