進口超高壓電磁閥，進口內螺紋高溫高壓電磁閥中國總代理

它廣泛應用于航天、船舶重工、石油化工、測試設備、清洗設備、加濕設備、液壓設備等，工作壓力在100MPa以上的管道系統中。

產品特點：
閥芯均為不銹鋼活塞式，活塞環不會被介質中的雜質卡死，動密封性能高,壽命長；活塞與金屬閥腔不產生直接摩擦，閥體安裝方向無限制；專制線圈，不易燒毀；長時間停用，動作同樣靈敏；最低啟動壓力1.0MPa。

主要技術參數：

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，閥腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。

規格尺寸：

注：出口端壓力大于進口端壓力，介質會反向導通。可安裝止回閥或訂制自帶止回功能的閥。

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.
