Who isn’t familiar with the situation? The call from the construction site, which in most cases does not bode well:
"The stem extension is too short!"
"We have to dig out everything again..."
"A different valve to the one given is installed."
"Everything has subsided, somebody didn‘t compact properly."
"The excavator operator didn‘t see the stem extension and knocked it over"
The telescopic stem extension can be immediately adjusted to the required length. If this is insufficient, you can extend it flexibly using the additional extension attachment.
No limitations due to different valve connections. Different adapter solutions for our bells adapt the stem extension to your house connection immediately.
If you find that the gate valve in the pipe trench has a different nominal size than you thought and thus a different stem connection, with the VariFix solution you always have the right coupling sleeve to clip on.
The stable pull-out lock prevents irreparable damage to the stem extension when pulled apart.
In the event of a pipe burst, the stem extension must be able to close a gate valve urgently and reliably. Top materials such as hot-dip galvanised steel or stainless steel prevent corrosion, large-volume bells prevent wandering of the sleeve tube and result in the operational reliability of BÜSCH stem extensions.
