德國萊克（LIK）品牌：進口高壓螺紋電磁閥廣泛應用在航天、船舶重工、石油化工、給排水、消防設備、食品醫(yī)療設備、清洗設備、景觀噴灌、加濕設備、液壓設備、測試設備、水廠等,工作壓力在6.4---100MPa的管道系統(tǒng)中。

產(chǎn)品特點：
閥芯均為不銹鋼活塞式，活塞環(huán)不會被介質(zhì)中的雜質(zhì)卡死，動密封性能高,壽命長；活塞與金屬閥腔不產(chǎn)生直接摩擦，閥體安裝向無限制；專制線圈，不易燒毀；長時間停止動作重新啟動，動作同樣靈敏；zui低啟動工作壓力0.5MPa。

主要技術(shù)參數(shù)：

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(zhì)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(guān)閉，閥腔由活塞節(jié)流孔增壓和復位彈簧的推力，電磁閥關(guān)閉。

Applications: 
Widely used in aerospace, shipbuilding Heavy Industry, petrochemical, water, fire fighting equipment, food and medical equipment, cleaning equipment, landscape irrigation, humidification equipment, hydraulic equipment, testing equipment, water plant, the work pressure in the pipeline 6.4 --- 100MPa system.

Features: 
Spool is stainless steel piston and piston rings will not be stuck impurities in the medium, dynamic sealing performance and long life; piston valve chamber with the metal does not produce direct friction, the valve installed to the limit; authoritarian coil, easily burned ; for a long time to restart the stopped action, action as sensitive; minimum start working pressure 0.5MPa.

Main technical parameters:

 

Specifications:	DN0.5 ~ DN200
Body material:	Stainless Steel
Medium:	Water, gas, oil, steam, gas, corrosive fluids
Temperature range:	-100 ~ +200 ℃
Media Viscosity:	Less than 50C St (greater than the time to be customized)
Protection performance:	Waterproof, explosion-proof (Exd IICT5), anti-corrosion
Wiring:	Terminal Block Type; lead type; male

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 throttle valve chamber pressurized by the piston return spring and 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, the piston on the lower chamber medium pressure to promote the solenoid valve open.
