首先，德國海隆（HERION）電磁閥的防爆標示EEx mdⅡCT6只是海隆公司產品隔爆的標識而已，其中md在Herion是封裝后再隔爆的意思，即整個線圈先用環氧樹脂進行澆封裹裝，再在外面加罩一層金屬防爆盒，4600系列為鋁合金的4800為不銹鋼的，整個線圈是用金屬外殼封裝一體式的。 其次，美國ASCO電磁閥的VCEF系列防爆標示EEx mdⅡCT6，其中md在ASCO是澆封防爆的意思，即整個線圈先用環氧樹脂進行澆封裹裝，再外接一個防爆接線盒，而這個線圈的核心部分其防護等級實際上為EEx mⅡT4，起隔爆作用的只是那個接線盒，但并沒有罩住線圈，也就是說并不是真正的防爆電磁閥。 再次，其次美國ASCO電磁閥的VCEF系列是在上海生產的，并非美國或是歐洲的，而德國海隆（HERION）電磁閥全部是德國原裝的，其質量和安全性能是遠高于VCEF系列。也就是說德國海隆電磁閥的EEx mdⅡCT6防爆等級是等同于美國ASCO電磁閥的EEx dⅡCT6防爆等級。美國ASCO電磁閥的NF和WSNF系列，是在線圈外面直接罩防爆接線盒的，這有別于HERION的先澆封后罩防爆接線盒的，即德國海隆（HERION）全金屬封裝后的EEx mdⅡCT6 防爆等級高于美國ASCO末封裝的全金屬外殼EEx dⅡCT6 的。 后，要電磁閥是不是真真防爆的不僅僅要看防爆等級，還要看起線圈和接線盒的位置，如果是接線盒罩住線圈的就是真真防爆的，如果線圈外接了接線盒就是澆封的，只是外接了一個防爆接線盒而已。 9711745.4600.02400閥 NORGREN諾冠herion海隆電磁閥 9710745.4600.02400 NORGREN諾冠herion海隆電磁閥 9713745.2050.00000 NORGREN諾冠herion海隆電磁閥 9711535.4040.02400 NORGREN諾冠herion海隆電磁閥 9711535.4603.23050 NORGREN諾冠herion海隆電磁閥 9710215.2050.00000 NORGREN諾冠herion海隆電磁閥 9713042.3039.0661374 NORGREN諾冠herion海隆電磁閥 9710535.2051.00000 NORGREN諾冠herion海隆電磁閥 9712535.2051.00000 NORGREN諾冠herion海隆電磁閥 9710505.4602.02400 NORGREN諾冠herion海隆電磁閥 9710505.4611.23050 NORGREN諾冠herion海隆電磁閥 9710505.3824.02400 NORGREN諾冠herion海隆電磁閥 9710505.3827.23050 NORGREN諾冠herion海隆電磁閥 9710505.3720.02400 NORGREN諾冠herion海隆電磁閥 9710505.3723.23050 NORGREN諾冠herion海隆電磁閥 9710505.0253.02400 NORGREN諾冠herion海隆電磁閥 9710505.3204.23050 NORGREN諾冠herion海隆電磁閥 9711505.0253.02400 NORGREN諾冠herion海隆電磁閥 9711505.3204.23050 NORGREN諾冠herion海隆電磁閥 9711505.3824.02400 NORGREN諾冠herion海隆電磁閥 9711505.3827.23050 NORGREN諾冠herion海隆電磁閥 9710505.2050.00000 NORGREN諾冠herion海隆電磁閥 9713545.2050.00000 NORGREN諾冠herion海隆電磁閥 9713545.2051.00000 NORGREN諾冠herion海隆電磁閥 9710505.2051.00000 NORGREN諾冠herion海隆電磁閥 9711535.4601.23050 NORGREN諾冠herion海隆電磁閥 9712535.4600.02400 NORGREN諾冠herion海隆電磁閥 9712032. 3062.02400 NORGREN諾冠herion海隆電磁閥 9710002.3039.02400 NORGREN諾冠herion海隆電磁閥 9710032.3050.02400 NORGREN諾冠herion海隆電磁閥 9711032.3050.02400 NORGREN諾冠herion海隆電磁閥 9710032.3039.00000 NORGREN諾冠herion海隆電磁閥 9712032.3039.00000 NORGREN諾冠herion海隆電磁閥 9710032.3039.02400 NORGREN諾冠herion海隆電磁閥 9710715.4600.02400 NORGREN諾冠herion海隆電磁閥 9710705.4600.02400 NORGREN諾冠herion海隆電磁閥 9710745.4803.23050 NORGREN諾冠herion海隆電磁閥 9710745.4611.23050 NORGREN諾冠herion海隆電磁閥 9710745.4200.02400 NORGREN諾冠herion海隆電磁閥 9710555.4600.02400 NORGREN諾冠herion海隆電磁閥 9710555.4602.02400 NORGREN諾冠herion海隆電磁閥 9713535.4602.02400 NORGREN諾冠herion海隆電磁閥 9710745.2050.02400 NORGREN諾冠herion海隆電磁閥 9711002.3039.02400 NORGREN諾冠herion海隆電磁閥 9710545.2050.00000 NORGREN諾冠herion海隆電磁閥 9710545.2050.00000 NORGREN諾冠herion海隆電磁閥 9711545.2050.00000 NORGREN諾冠herion海隆電磁閥 9713765.4600.02400 NORGREN諾冠herion海隆電磁閥 9710765.4600.02400 NORGREN諾冠herion海隆電磁閥 9713755.2051.0000 NORGREN諾冠herion海隆電磁閥 9710635.4603.23050 NORGREN諾冠herion海隆電磁閥 9710635.4601.23050 9711745.4600.02400閥
