Installation & Initial Operation
Limiting the Presetting
Even with a limited
presetting, the valve
can still be set to zero
or shut off.
The preset value can be limited
or fi xed (see Fig. 11). This me-
ans that after shut off (hand-
wheel set to zero) the previ-
ous value can be quickly found
again and reset.
1. Insert the long end of an
Allen wrench (3 mm) into
the center hole on the
handwheel face (Fig. 11).
2. Turn the key clockwise as
far as it will go in order to
limit the adjusting spindle
