進(jìn)口低溫電磁閥-進(jìn)口（制冷劑、液氮、液氧、二氧化碳）

德國威樂WILO品牌：進(jìn)口低溫電磁閥應(yīng)用范圍：
它廣泛應(yīng)用于航天、船舶重工、化工、冷凍設(shè)備、食品醫(yī)設(shè)備等制冷管道系統(tǒng)中。

產(chǎn)品特點：
閥芯均為不銹鋼活塞式，活塞環(huán)用特殊耐低溫、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，不易燒毀；長時間停止動作重新啟動，作同樣靈敏。

主要技術(shù)參數(shù)：

產(chǎn)品規(guī)格：	DN0.5～DN500
閥體材質(zhì)：	不銹鋼
適用介質(zhì)：	制冷劑、液氮、液氧、液氬、二氧化碳等
溫度范圍：	-200～+150℃
介質(zhì)粘度：	小于50C St(大于時需定制）
防護(hù)性能：	防潮、防爆（Exd IICT5)、防腐
接線方式：	接線座式；引線式；插頭式
控制方式：	常開、常閉
電源電壓：	DC24～127V; AC36～380V
連接方式：	內(nèi)螺紋、法蘭（外螺紋和特殊接口可定做或加轉(zhuǎn)接頭）

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，閥上腔卸壓，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，電磁閥關(guān)閉。

Applications:
It is widely used in aerospace, shipbuilding Heavy Industry, chemical, refrigeration equipment, Medical equipment, food refrigeration piping systems.

Features:
Spool is stainless steel piston, piston ring with a special low temperature resistant, wear-resistant material; the piston and the metal does not produce direct friction valve chamber, valve mounting direction unlimited; special coil, not easy to burn; a long time to stop action to re-start, for the same sensitivity.

Main technical parameters:

Specifications:	DN0.5～DN100 DN0.5 ~ DN100
Body material:	Stainless Steel
Medium:	Liquid nitrogen, gas, oil, steam, corrosive fluids
Temperature range:	-200 ~ +150 ℃
Media Viscosity:	Less than 50C St (greater than the time to be customized)
Protection performance:	Moisture-proof, explosion-proof (Exd IICT5), anti-corrosion
Wiring:	Terminal Block Type; lead type; male
Control:	Normally open, normally closed
Power supply voltage:	DC24 ~ 127V; AC36 ~ 380V
Connection:	Thread, flange (male and special interfaces or add custom adapter)

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, the valve chamber and pressurized by the piston return spring throttle 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.
