Honeywell Actuator LKS130-10 (B6-5S1) LKS130-10

This servo motor actuator positions air dampers by converting a control signal into rotational movement. It is designed for burner, boiler, and heating systems to modulate airflow. The unit operates on 220 V, has a torque of 75 Nm, and reaches 90° in 5 seconds. Power consumption is 9 W, protection class is IP31, and the flap type is air. Dimensions are 8.5x6x13.2 cm and weight is 550 g.

Actuators of this type are selected by required torque, running time, control signal type (commonly three-point, 0-10 V, or on/off), shaft or coupling pattern, angle of rotation, and presence of auxiliary switches. Before ordering, compare these specifications with the existing installation. For systems using three-way or four-way mixing valves, verify compatibility with the valve interface and torque requirements; the valve body and actuator are often separate spare parts.

Typical failure modes include a stripped gear train, a failed end switch, or a seized valve stem, particularly if the valve has remained stationary for a prolonged period. Such faults can stop the actuator from moving the connected damper or valve.
