Belimo's fast-acting rotary actuators, including the LMQ, NMQ, NMD, SMQ, SMD, and NKQ ranges, offer a versatile solution for damper control. With nominal voltages of 24V and 230V, these actuators ensure precise operation within 2.5 to 20 seconds for a 90° turn. They cater to dampers from 0.8m² to 3.2m², delivering nominal torques between 4Nm and 16Nm. The NKQ fail-safe actuators provide added reliability with a 4-second run time, suitable for 1.2m² dampers at 6Nm torque.
