2.2.3 Replacing a damaged tapping valve
CAUTION!
A hole must be drilled in accordance with Ä Chapter 3.4.3
‘Tapping the supply line’ on page 20 to make a tight con‐
nection. The tapping valve must not be positioned at the
location of an existing hole. When a Viega tapping valve is
replaced, the new tapping valve must not be placed in the
position of the previously dismounted tapping valve.
Failure to comply may cause a leak in the connection to
the supply line.

2.3.3 Tapping valve
Fig. 2: Components tapping valve
1 Spindle
2 Tapping / valve casing
3 Outlet sleeve with clamping ring
4 Pipe clamp bottom piece
5 Pipe clamp top
Geopress tapping valves are made of high-quality plastic. They are
equipped with an outlet sleeve for Geopress K.
The fitting is pressed onto the supply line. A spring set in the bottom
part of the pipe clamp keeps the pressing force on the pipe at a con‐
stant level. The integrated cutter is connected to the actuating spindle.
The cutter is used for tapping and subsequently remains in the fitting.
The cutter holds the cut-out pipe wall plate securely. The sleeve in the
drill hole prevents the tapping valve from twisting on the supply line.
The model is equipped with an operation shut-off for the house service
connection. The spindle acts as a drilling rod during tapping, and after
commissioning as an actuating spindle for the shut-off.

2.3.4 Mark on tapping valves
The model has a mark for alignment on the supply line.
The position of newly laid pipes and connection lines, including detailed
information about pipeline parts, must be documented and regularly
updated. The traceability code on the tapping valve allows every con‐
nector to be traced back and simplifies the documentation in as-com‐
pleted drawings.

The tapping valve is integrated into the Viega product network. At the
outlet of the tapping valve, the house service connection is connected
by means of a connecting piece or connection elbow.

3 Handling
3.1 Transport
Leave the fitting in the original box, in this way spare parts important for
mounting won't get lost.
3.2 Storage
Remove the protective foil during mounting, as described in the
mounting instructions Ä Chapter 3.4.1 ‘Pressing onto the supply line’
on page 16.
3.3 Assembly information
3.3.1 Mounting instructions
The design of the tapping valve for d 63 is different from
the other pipe sizes. The pressing takes place on the
opposite side of the outlet sleeve.
Pipes must be visually inspected for the following damage before instal‐
lation:
nOvalities: threshold values must not be exceeded, see Ä ‘Regula‐
tions from section: Notes on mounting’ on page 6.
This is valid for coiled bundles as well as rods.
nDents
nCracks
nGrooves (maximum depth 10 % of nominal wall thickness)
Only process the sections of the pipes, which do not exhibit these fea‐
tures.
The following components must be included:
nTapping valve
nclamping ring
nLocking pin for clamping ring and a replacement pin
nFixing bolts for tapping valve
Check scope of delivery

3.3.2 Space requirements and intervals
Adequate space is a prerequisite for mounting. Only carry out the
pressing when the hinged adapter jaw (model 2296.2 or 0796.2, Z2) or
Geopress hand press tool is placed exactly in the seat of the tapping
valve.
For the Z dimensions, refer to the respective product page in the online
catalogue.
3.3.3 Required tools
The following tools are required for mounting the tapping valve:
nBattery-powered press machine:
nPressgun 5 or
nPressgun 4B
nhinged adapter jaw Z2 (model 2296.2 or 0796.2)
nalternative: Geopress hand press tool (model 9696.5)
