Mounting the actuator
1. DiaphragmactuatorDN15to100
Insert the actuator stem (11) through the
hole in the crossbeam (8) into the travel
stop cap with cotter pin (20) and fasten
the actuator with the nuts (9). Observe
thetighteningtorquesspeciedinthethe
Annex.
− BellowsactuatorDN15to50
Insert the actuator stem (11) into the trav-
el stop cap with cotter pin (20).
Align actuator on the pillars (8.1) and
fasten it with the nuts (8.2). Observe the
tighteningtorquesspeciedinthethe
Annex.
− BellowsactuatorDN65to100
Screw the pillars (8.1) into the threaded
holes(8.3)oftheactuatorangeasfar

cause components to move in an uncon-
trolled manner resulting in injury to hands or
ngers.
