進口超低溫電磁閥

美國米勒(miller)品牌：進口超低溫液氮電磁閥|-196℃電磁閥主要使用于制冷劑  ,液態二氧化碳,液氨,液氧,液氮,氟里昂等低溫流體的管路上，是設備系統控制中氣體、液體、油類等各種管道介質的自動化控制，實現節能和程序控制自動化。是自動控制系統中常見的管路開關元件，被廣泛使用于冷凍庫、石油化工、暖通空調、消防、冶金、紡織、船舶重工、環保及其他各工業部門的管路裝置中。

產品特點：

1、采用原裝密封材料，壽命是同類產品十倍

2、數控機床加工，確保電磁閥的精度與可靠性

3、液體、氣體、油品可混合使用，提高閥的使用范圍

4、采用專用塑封線圈，提高閥的可靠性并能防水、防潮

5、現場可自由安  裝；動作響應迅速；閥體采用熱鍛成型工藝、外型美觀

6、活塞環用特殊耐低溫、耐磨材料制作；活塞與金屬閥腔不產生直接摩擦，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

7、安  裝提示：最好線圈豎直向上，也可根據需要任意安  裝

主要技術參數：

產品規格：

dn0.5～dn100

閥體材質：

不銹鋼

適用介質：

液氮、氣、油、蒸汽、腐蝕流體等

溫度范圍：

-200～+150℃

介質粘度：

小于50c st(大于時需定制）

防護性能：

防潮、防爆（exd iict5)、防腐

接線方式：

接線座式；引線式；插頭式

常開、常閉

電源電壓：

dc24～127v; ac36～380v

連接方式：

內螺紋、法蘭（外螺紋和特殊接口可定做或加轉接頭）

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，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。

常開：當線圈通電時，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。當線圈斷電時，先導閥芯靠彈簧復位，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。

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, 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【敏感詞】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:

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【敏感詞】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【敏感詞】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.

note: the outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. can be installed【敏感詞】custom built non-return valve function of the valve.
