and needle bearing with axial disk (7.4)
onto the spigot of the actuator bellows
(5.1).
3. DN 15 to 50 without balancing bellows:
Use an Allen key (4 mm) to hold the bel -
lows extension stationary and screw on
the nut (7.2). Tighten the cap screw (7.3)
to fix the nut in position. Observe the
tightening torques specified in sec
-
tion 7.5.
DN 65 to 100 without balancing bel -
lows and DN 15 to 100 with balancing

7.3 Replacing the seat and
plug
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the specified tightening torques.
Make absolutely sure that no torque is
applied to the bellows seal (5.1) during
assembly or disassembly. Otherwise, the
metal bellows will be destroyed.
