進(jìn)口超高壓電磁閥德國(guó)托克TOK品牌：進(jìn)口超高壓電磁閥應(yīng)用范圍：它廣泛應(yīng)用于航天、船舶重工、石油化工、測(cè)試設(shè)備、清洗設(shè)備、加濕設(shè)備、液壓設(shè)備等，工作壓力在100MPa以上的管道系統(tǒng)中。
產(chǎn)品特點(diǎn)：
閥芯均為不銹鋼活塞式，活塞環(huán)不會(huì)被介質(zhì)中的雜質(zhì)卡死，動(dòng)密封性能高,壽命長(zhǎng)；活塞與金屬閥腔不產(chǎn)生直接摩擦，閥體安裝方向無(wú)限制；專制線圈，不易燒毀；長(zhǎng)時(shí)間停用，動(dòng)作同樣靈敏；zui低啟動(dòng)壓力1.0MPa。
主要技術(shù)參數(shù)：

工作原理：
常閉：當(dāng)線圈通電時(shí)，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(dòng)，電磁閥打開；當(dāng)線圈斷電時(shí)，先導(dǎo)閥芯靠彈簧復(fù)位，先導(dǎo)孔關(guān)閉，閥腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力，電磁閥關(guān)閉。

Applications: 
It is widely used in aerospace, shipbuilding Heavy Industry, petrochemical, test equipment, cleaning equipment, humidification equipment, hydraulic equipment, the work of more than 100MPa pressure pipeline 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 mounting direction unlimited; authoritarian coil, easily burned ; for a long time disabled, the same movement sensitive; minimum starting pressure 1.0MPa.
Main technical parameters:

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, medium pressure piston push the lower chamber, the electromagnetic valve is opened.
Size:

Note: The outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. Can be installed or custom built non-return valve function of the valve.
