5.2.1 Ball valve
If the actuator is already installed to the valve, you can skip the points 1-5
NOTE:
If working in potentially explosive atmosphere all related safety and work instructions
must be followed.
Any tools or working methods generating sparks or extensive heat are not allowed
without written permission from responsible personnel.
Please check the actuator’s position before mounting it on the valve.
Please also check that the top flange and the valve stem are perpendicular to each other
and that there are no impurities between the actuator and the valve. Impurities or wrong
position between the top flange and valve stem might damage the actuator.
Installing the actuator
Part numbers refer to the figure 4
1. Vexve ball valves are delivered from the factory in the open position. If the valve has been operated
so that it is in some other position, turn the valve to the open position.
2. Check that the valve stem (4) is intact and clean. Check also that the key (5) of the valve stem is
properly in its groove
3. Turn the actuator to the open position
4. Install the actuator on the valve. Note that the actuator is equipped with one key way so it is not
possible to change its installation position on the valve. The key way of the actuator must fit the
stem easily and you must not force it in its place
Grease the attachment screws (2) of the actuator. Put all the washers (3) and the attachment screws (2)
first loosely in their places and finally tighten them up
Angle adjustment
NOTE:
Adjust the angle so that it exceeds the actual OPEN and CLOSE positions of the valve
evenly.
Part numbers refer to the figure 5
5. Open the fastening screws (1). Adjust the correct OPEN position by loosening the other and
tightening the other angle adjustment screw (2). Tighten the fastening screws (1)
6. Turn the valve slightly towards the close position and then back to the open position against the
limit. Check if the OPEN position is correct. If it is not correct, repeat the steps 6 and 7
7. Check that the valve opens and closes correctly
