▶Das Gerät dient ausschließlich als Magnetventil für die lt. Daten-
blatt zulässigen Medien und für den Einsatz in Explosionsgruppe
IIC, Kategorie 2G und Temperaturklasse T4 oder T6
(siehe Angaben auf dem -Zulassungsschild).
▶Die Magnetspule ist in zwei mechanischen Ausführungen lieferbar:
- Auf / Zu-Version
- proportionalwirkende Version (Magnetkern öffnet abhängig
vom anliegenden elektrischen Strom.)
Beide Magnetsysteme sind rein mechanische Varianten, die sich
in den sicherheitstechnischen Daten nicht unterscheiden.
▶Die angewandte Schutzart ist die Vergusskapselung Ex mb
für Spulen mit Kabelanschluss oder die Vergusskapselung mit
erhöhter Sicherheit Ex e mb für Spulen mit Klemmenkasten.
▶Die Magnetspule Typ 7..-... dient zum Betätigen von Ventilen, die
gasförmige oder flüssige Medien steuern. Die Spule ist entwe-
der mit dem Kernführungsrohr der Armatur vergossen oder sie
wird mit dem Kernführungsrohr der Armatur montiert und mittels
einer Mutter befestigt. Es entsteht immer ein geschlossenes
System und die Geräte dürfen auch in Tanksäulen zur Steue-
rung von Benzin als Kategorie-2-Gerät eingesetzt werden. Die
Ventilkörper können wahlweise aus Metall oder Polyamid sein.
▶Der einwandfreie und sichere Betrieb des Systems setzt
sachgemäßen Transport, sachgemäße Lagerung und Installa-
tion sowie sorgfältige Bedienung und Instandhaltung voraus.
