Ball Valves X-Series


The new X-series from Vexve is the result of continuous product development and optimization.
Compared to the previous standard ball valves, the tightness of the bore has been further improved
while at the same time reducing the actuating torque and increasing the flow rate.

A real innovation is the new hand lever made of high-quality composite materials, which can be removed and fitted without tools.
The hand lever is also a spindle extension, making it easier to isolate the ball valve.
In the unlikely event of medium escaping from the spindle, the medium is guided through the handle into the area outside the insulation,
reliably preventing undetected corrosion inside the insulation.

All important product features of the ball valve can be read on the top of the hand lever - and therefore outside the insulation
and all product-related information can be easily found using the included QR code.

The new product range has replaced almost all existing valves in the DN 10-50 size classes.
The complete range includes shut-off and balancing valves made of steel and stainless steel with the most common bore types.

The Vexve X-Series steel or stainless steel ball valves can be used in a variety of process control applications,
such as heating and cooling systems and are particularly suitable for district heating, district cooling, compressed air and oil networks.

FAQ - Häufig gestellte Fragen zu Kugelhähnen X-Serie



Was ist die Vexve X-Serie?
Die X-Serie ist die aktuelle Generation der vollverschweißten Kugelhähne von Vexve für DN10 bis DN50 in PN40. Sie hat in dieser Größenklasse fast alle bisherigen Ausführungen ersetzt. Das Programm umfasst Absperr- und Strangregulierventile aus Stahl und Edelstahl mit den gängigen Anschlussarten.
Was ist gegenüber den Vorgängerbaureihen besser?
Die Dichtheit im Durchgang wurde verbessert, die Durchflusswerte sind höher und das Betätigungsmoment ist geringer. Der Handhebel aus Verbundwerkstoff lässt sich ohne Werkzeug abnehmen und montieren und dient zugleich als Spindelverlängerung. Das erleichtert die Isolierung der Armatur.
Warum ist der Handhebel zugleich Spindelverlängerung?
Tritt an der Spindel Medium aus, führt der Handhebel es nach außerhalb der Isolierung, wo es sichtbar wird. So bleibt Korrosion unter der Dämmung nicht unentdeckt. Auf der Oberseite des Hebels stehen die wichtigsten Produktdaten, ein QR-Code führt zu den weiteren Informationen zur Armatur.
Welche Anschlussarten und Betätigungen gibt es?
Lieferbar sind beidseitige Schweißenden, beidseitig Innengewinde, beidseitig Flansch sowie die Kombinationen Schweißende/Innengewinde, Schweißende/Flansch und Schweißende/Außengewinde mit Kette und Kappe. Der Durchgang ist je nach Ausführung voll oder reduziert. Betätigt wird per Handhebel oder Handgetriebe.
Für welche Anwendungen ist die X-Serie gedacht?
Für Heiz- und Kühlsysteme sowie Druckluft- und Ölnetze, also Fernwärme, Fernkälte, Heizwarmwasser und Klima-Kaltwasser. Die Kugelhähne sind wartungsfrei, bi-direktional dicht nach EN 12266-1, Leckrate A, und in Stahl oder Edelstahl erhältlich. Gängige Ausführungen sind ab Lager Burscheid lieferbar.
