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.
真空電磁閥是安裝在機(jī)械式真空泵上的閥門(mén)。
閥門(mén)與泵接在同電源上，泵的開(kāi)啟與停止直接控制了閥的開(kāi)啟與關(guān)閉。
當(dāng)泵停止工作或電源突然中斷時(shí)，閥能自動(dòng)將真空系統(tǒng)封閉，并將大氣通過(guò)泵的進(jìn)氣口充入泵腔，
避免泵油返流污染真空系統(tǒng)。真空電磁閥適用的工作介質(zhì)為空氣及非腐蝕性氣體。

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)
