Wall bracket and mounting plate 7.3.
(optional)
Ensure that the plastic ball valve is bonded securely in the pipeline
system.
An appropriate bracket supports the net weight of the plastic ball valve
and absorbs the tension resulting from operation of the system.
The plastic ball valve is attached via an extruded bracket into which
stainless steel threaded bushings can be pressed (accessories).
Attach the plastic ball valve to an appropriate substructure with
→
standard screws.
A mounting plate ( Fig. 8: ), which is available as an accessory, can be
used for the wall-mounted installation of the 2-way model.
Before fitting the mounting plate to the wall, attach it to the bracket
→
of the plastic ball valve with screws.
The dimensions of the screws required for attachment correspond with
those of the threaded inserts in the ball valve.
