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!
