FUNCTIONAL DESCRIPTION
LK 950 is a series of compact actuators designed to motorize rotary
mixing valves. The actuator is controlled by means of a modulating
signal 2 (0)-10 VDC. LK 950 fits most rotary valves. Alternative moun-
ting kits can be supplied as option.
OPERATION
The actuator can be mounted in any position except below the
valve. Thanks to its small size and compact form the LK 950 fits
most installations.
The actuator is mounted directly onto the valve spindle with a screw. An
anti-rotation bolt is screwed
onto the valve. The angle of rotation is limited to 90°. When the actuator
reaches either end position the voltage supply is interrupted by limit
switches. The actuator can be put into manual mode by turning the but-
ton on the housing cover which will disengage the gears. The actuator
can now be put in any position by turning the handle on the front and
this position is indicated by means of a reversible scale.
MOUNTING INSTRUCTION
1. Turn the spindle of the valve A counter clockwise to the end posi-
tion (OPEN or CLOSED). Remove the handle supplied with the valve
body from the valve spindle.
2. Screw the anti-rotation stop B in a convenient hole on the valve (if
necessary remove an existing screw).
3. Slide the linkage C over the valve spindle.
4. Place the actuator D onto the linkage C and if necessary rotate it
slightly clockwise until the antirotation stop B engages in the slot of
the actuator (the actuator is supplied in the anti-clockwise position).
5. Turn the scale E into the position relevant to the

6. Place the handle F onto the actuator ensuring that
the arrow points to the left end position of the scale.Tighten the
whole unit by means of the screw G.
7. Using a screwdriver (No. 3) turn the disengaging button on the
housing cover from «A» to «Hand Symbol» position and rotate the
valve by means of the handle F from one end position to the other.
It is important that the actuator can be moved from one end stop
to the other (90°).
8. Connect the actuator to the power supply.
9. Turn the disengaging button back to the«A» position and the
actuator will turn in the required position.
