隔爆外壳存在间隙，因电气设备呼吸作用和气体渗透作用，使内部可能存在爆炸性气体混合物
Ingress protection degree IP65 Enclosure provided with integral strain relief for cables with an o.d. from 6 to 10 mm
A wide range of valves can be supplied with the operator
Application of the operator, located within hazardous areas, is not permitted without the addition of an approved
and classified device (such as barriers) located between the safe and hazardous area
The operator can be rotated 360° to select the most favourable position for cable entry
防爆电磁阀是把设备可能点燃爆炸性气体混合物的部件全部封闭在一个外壳内，
This highly efficient solenoid operates at very low power level (0.4W)

temperature is -40°C for the operator. Select the requested "T" classification from the temperature
classification tables (AC or DC), respecting the maximum ambient temperature and cold (20°C) electrical holding power values.
把可能产生火花、电弧和危险温度的零部件均放入隔爆外壳内，隔爆外壳使设备内部空间与周围的环境隔开。
Multi language installation/maintenance instructions are included with each valve
The solenoid operators can be mounted in any position without affecting operation简单介绍美国ASCO本安型防爆电磁阀
