Absperrventil<\/strong><\/p>\n\n\n\n

Das DFI-Explosionsschutzventil<\/strong> arbeitet passiv (durchflussaktiviert), d. h. es ist keine externe Energie erforderlich, um die Ventilklappen zu schlie\u00dfen, wenn eine Verpuffung auftritt. Wenn w\u00e4hrend des normalen Betriebs Prozessluft str\u00f6mt, zieht oder dr\u00fcckt die Luft die Ventilklappen auf, so dass Luft aus dem Prozess in das gesch\u00fctzte Ger\u00e4t str\u00f6men kann. Kommt es in der gesch\u00fctzten Anlage zu einer Deflagration, kehrt der erzeugte Explosionsdruck den Prozessluftstrom um, schlie\u00dft die Ventilklappen und verhindert das Eindringen der Deflagrationsflammenfront.<\/p>\n\n\n\n

Das DFI-Explosionsschutzventil<\/strong> wurde gem\u00e4\u00df den Anforderungen von NFPA 69 und EN 16477 konstruiert. Zu den Hauptkomponenten des Ventils geh\u00f6ren eine hochbelastbare, geschwei\u00dfte Stahlkonstruktion, zwei Absperrklappen, abnehmbare Inspektionsklappen, Klappenverriegelungen und Ratschenpositionsanzeigesensoren zur Prozessunterbrechung.<\/p>\n\n\n\n

Breites Anwendungsspektrum, geeignet f\u00fcr fast jede Anwendung, findet er in fast allen Branchen Verwendung.<\/p>\n\n\n\n

Zuverl\u00e4ssiger doppelter Verriegelungsmechanismus<\/strong><\/p>\n\n\n\n

Im Gegensatz zu anderen Klappenventilen, die identische Flammenisolationstests nicht bestanden haben, h\u00e4lt es nachweislich den Druckunterschieden und Schwingungen stand, die eine geschlossene Klappe \u201edr\u00fccken und ziehen\u201c.<\/p>\n<\/div>\n\n\n\n

\n
\"\"\/<\/figure>\n\n\n\n

Flexible Installation<\/strong><\/p>\n\n\n\n

Es ben\u00f6tigt nur wenig Platz und kann sowohl horizontal als auch vertikal eingebaut werden. Es kann n\u00e4her am Tank angebracht werden als andere Klappenventile.<\/p>\n<\/div>\n\n\n\n

Breites Spektrum an Schutzm\u00f6glichkeiten<\/strong><\/p>\n\n\n\n

Er h\u00e4lt den hohen Dr\u00fccken stand, die mit fast allen Arten von St\u00e4uben verbunden sind: ST1 organische St\u00e4ube (Getreide, Kohle, Zucker, Mehl), ST2 organische St\u00e4ube (chemische, pharmazeutische) und Metallst\u00e4ube (Aluminium, Eisen, Zink und andere Legierungen).<\/p>\n<\/div>\n<\/div>\n\n\n\n
