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.
