the positioner and the pin inserted into the
lever.
The travel tables on page Seite 26 show
the maximum adjustment range at the posi-
tioner. The travel that can be implemented at
the valve is additionally restricted by the se-
lected fail-safe position and the required
compression of the actuator springs.

(pin position 35) as standard (see Fig. 4).
The M lever is included in the scope of deliv -
ery.
S, L, XL levers are available as accessories.
The XXL lever is available on request.
