進口中低壓電磁閥產(chǎn)品特點：

1、電磁閥內(nèi)部組件均為不銹鋼制造，采用數(shù)控加工中心制成，控制尺寸精度高，產(chǎn)品互換性好。

2、活塞環(huán)采用耐磨特殊材料，伸展自如，不會被介質(zhì)中的雜質(zhì)卡死，具有自動間隙補償功能，動密封性能高。

3、金屬活塞與金屬閥腔不產(chǎn)生直接摩擦，活塞壽命增長，可連續(xù)動作百萬次以上。

4、閥體的安裝方位不受限制，垂直、水平、傾斜都可以。

5、專制線圈，線圈不易燒毀。合理的密封結(jié)構(gòu)，密封性能更好。

6、長期停止動作后的重新啟動，動作同樣靈敏。

進口中低壓電磁閥工作原理：

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(fù)位，先導孔關(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。

Working principle of imported medium and low pressure solenoid valve:

Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure in the upper chamber of the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened.

When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.

Normally open: when the coil is energized, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
