Setting of end stop OPEN
The swing angle has been set in the factory to approx. 90° or to the swing
angle stated in the order. An adjustment might be necessary if the end stop
CLOSED has been re-adjusted.
.
Check whether mechanical end position of the valve corresponds to the
mechanical end stop of actuator by turning at handwheel
(counter-clockwise for end position OPEN)
.
If necessary, remove screw plug (22.2, figure B2) and adjust mechanical
end stop at hex. socket head cap screw (21.2, figure B2).
.
Check O-ring in screw plug and replace if damaged.
.
Replace and fasten screw plug (22.2).

Setting values for mechanical end stops
The limitation of travel is realised via limit switches
(page 11) in both end positions. For this reason the end
stops of the actuator have to be set to a slightly larger swing
angle (approx. by 2° larger) than the swing angle actually
required by the valve.

1) By turning at the hex. socket head cap screw for end stop CLOSED or OPEN the end
position changes accordingly.
The swing angle can be checked and set by using the dimension T.

For each turn of the hex. socket head cap screw, the setting of the end
position changes by:
