Valve Actuator

LK 950 Valve Actuator

• Up to 10 Nm

• Wide range of products

LK 950 is a series of valve actuators. Depending on model the

actuator can be operated by a controller with a 3-point SPDT

output or a proportional 2 (0) - 10 V output. The actuator is fitted

with limit switches. The angle of rotation is electrically limited

to 90°. An additional auxiliary adjustable switch can be ordered

as an accessory.

The actuator can be mounted in any position except below the

valve. The actuator is mounted directly onto the valve spindle

with a screw. An anti-rotation bolt keeps the actuator in posi-

tion. When needed, the actuator can be put into manual mode

by turning the button on the housing cover 90° clockwise to dis-

engage the gears. The actuator can now be put in any position

by turning the handle on the front. The position is indicated on

the reversible scale.

LK 950 fits most mixing valves. Mounting kits for mixing valves

of other brands are availabale - please see the product sheet for

Mounting Kits.
