Fig. 10-A:
- Turn flat hexagon nut if not present on valve stem.
Fig. 10-A/B:
- Slip coupling (pos. 50.27) over valve stem.
- Screw threaded bush (pos. 50.87) matching the valve onto
the valve stem in accordance with setting dimension (Y)
and lock with hexagon nut
- Setting dimension (Y) for fitting-projection (X)
83mm = 102mm.
- Setting dimension (Y) for fitting-projection (X)
98mm = 116mm

ATTENTION !
X = 60/83mm --> Y = 102mm
(+2mm)
X = 98mm --> Y = 116mm
(+2mm)
ATTENTION !
Setting dimension (Y) and fitting-projection (X)
are measured with inserted valve stem. This
means for
- 2-way valves at closed valve,
- 3-way valves with mixing plug at closed
way B,
- 3-way valves with diverting plug at closed way
A
After measuring put the valve plug back in the
mid lift position!
