Mounting to valve
.
Prior to mounting the part-turn actuator must be checked
for any damage.
.
Damaged parts must be replaced by original spare parts.
.
After mounting to valve, touch up any possible damages
to paint finish.
.
For butterfly valves the recommended mounting position is end position
CLOSED.
(Prior to mounting, bring the part-turn actuator to the mechanical end stop
CLOSED by turning the handwheel clockwise).
.
For ball valves the recommended mounting position is end position
OPEN. (Prior to mounting, bring the part-turn actuator to the mechanical
end stop OPEN by turning the handwheel counter-clockwise).
.
Thoroughly degrease mounting faces of part-turn actuator and valve.
.
Place coupling sleeve on to valve shaft and secure
(refer to figure A2, detail A or B), ensure that dimensions X, Y and Z are
observed (refer to table 2).
.
Apply non-acidic grease at splines of coupling.
.
Fit actuator so that fixing holes in actuator and valve mounting flange are
in alignment.
If necessary, move actuator up or down one tooth on the coupling.
If required, turn handwheel a little in direction OPEN or CLOSE until holes
align to the threads.
.
Ensure that the spigot (if provided) mates uniformly in the recess and that
the mounting faces are in complete contact.
.
Fasten the actuator with bolts of minimum quality 8.8 using lock washers.
Fasten bolts crosswise to the appropriate torque according to table 2.
