must be followed.
Any tools or working methods generating sparks or extensive heat are not allowed
without written permission from responsible personnel.
5.1 Disassembly
Part numbers mentioned in this chapter refer to
the figure 4.
1. Ball valves: Turn the valve to the open
position (counter-clockwise) before
removing the actuator (1).
Butterfly valves: Turn the valve to the
close position (clockwise) before removing
the actuator (1).
Valve opens by pumping hydraulic oil into
connection “B” and closes when hydraulic
oil is pumped into connection “A”. Use a
hand pump or a hydraulic power unit
2. Turn the actuator slightly backwards to
release forces between the valve and
the actuator in order to make it easier to
remove the actuator:
Ball valves: Turn the actuator slightly
towards the close position (clockwise)
by pumping a little hydraulic oil into
connection “A” until pressure level is low
Butterfly valves: Turn the actuator slightly
towards open position (counter-clockwise)
by pumping a little hydraulic oil into
connection “B” until pressure level is low
3. Remove any position indicator if used
4. Remove the attachment bolts (2) of the
actuator and remove the actuator (1)
Reinstallation instructions for ball valves see
chapter 5.2.1 steps 1-5 and for butterfly valves,
see chapter 5.2.2 steps 1-5.
