The valves shall be provided with an electrical circuit which ensures the
limits of the harmonised standards EN 61000-6-3 and EN 61000-6-1 are
observed, and hence the requirements of the Electromagnetic
Compatibility Guideline (2004/108/EG) satisfield.
真空电磁阀是安装在机械式真空泵上的专用阀门。
阀门与泵接在同一电源上，泵的开启与停止直接控制了阀的开启与关闭。
当泵停止工作或电源突然中断时，阀能自动将真空系统封闭，并将大气通过泵的进气口充入泵腔，
避免泵油返流污染真空系统。真空电磁阀适用的工作介质为空气及非腐蚀性气体。

High flow rate
For robust industry solutions
The conditions imposed on the Ex approvals lead to reduction of the permissible
standard temperature ranges in the cases of explosion protected solenoids.
*1) Up to max. +200°C fluid temperature with solenoid for higher temperature
*2) Only d.c., for a.c. solenoids with design inspection certificate
acc. to category 2, e.g. XXXXXX.8436
Damped operation
Suitable for vacuum
Valve operates without differential pressure (Zero delta P)
