3.3 The maximum working pressures and temperatures are indicated in
the valve identification plate.
3.4 Make sure before installation has the suitable tools.
3.5 Do not remove the protective covers of the connections until just before installation.
4. Welding.
4.1 Is necessary a clean area for work.
4.2 Genebre, S.A. recommends the use of electric welding methods (TIG, MIG).
4.3 Use cooling during the welding process.
4.4 Welding to be performed by a qualified welder.
4.5 Excessive heating of the valve must be avoided during the welding.
4.6 When the valve is installed in a horizontal piping, it must be in the open position for

4.7 When the valve is installed in a vertical piping, the valve shall be open when the
upper seam is welded and when the lower seam is welded the valve shall be closed.
4.8 Do no open/close the valve immediately after welding. Wait the valve cool before
operating it.
4.9 If is necessary to make the pressure test Genebre, S.A. recommend use the
instruction of European Standard EN 12.266 part. I.
Hydraulic test from seat should be 1,1 PN with closed valve position.
Hydraulic test from body should be 1,5 PN with partly open valve position (45º).

5. Operation.
These types of valves (floating ball) was designed for use as a shut-off, may only be used
in the open-closed position.
In applications where the valve remains in the same position for much time, is
recommended to open or close a few times during the year to avoid hardening of the
valve.
The same at other models of ball valves from Genebre, S.A. the operation is:
CLOCKWISE for closed valve.
COUNTER CLOCKWISE for open valve.
In sizes >= to DN 200 the valves has install a Gear Operator for open - closed the valve.
If is necessary the adjusting from this remove the bolt pos. 14 from gear operator and
regulate the blot pos. 13. according to necessity.
