Branching Ball Valves / Ball Valves for Network Expansion
The Vexve branching ball valve (type NAVAL) is used to complete a construction section that will be continued at a later date.
Branching ball valves are welded in at points where future connections are planned.
New consumers can be connected to the system without the pipeline having to be drained and taken out of service.
In order to avoid any contamination and to prevent PUR-foam from penetrating the open end of the branching valve,
a torispherical head or cap in accordance with DIN 2617 is provided.
If no branching ball valve has been installed, we recommand our innovative hot tapping system
as an uncomplicated and safe alternative for creating a new connections during operation.
You can find more information on the hot tapping process on our pages hot tapping tools and hot tapping service.
Applications branching ball valve
- end piece of a pipe system to prepare future connections
- enable installation without interrupting the supply or draining the system (see also hot tapping ball valves)
- suitable for all non-aggressive media, such as district heating or cooling water, oil and compressed air
- operating conditions according to data sheet
