LK 951 is a series of compact valve actuators. Depending
on model the actuator can be operated by a controller with
a 3-point SPDT output or a proportional 0 - 10 V output. The
angle of rotation is limited to 90°.
LK 951 can be mounted in any position except below the valve.
The actuator is fitted directly onto the valve spindle with a
screw. An anti-rotation bolt keeps the actuator in position.
When needed, the actuator can be put into manual mode by
pressing the handle. The actuator can now be put in the desired
position. The position is indicated on the reversible scale.
LK 951 fits most mixing valves.
