Product Details

Belimo Modulating Damper Actuator

The Belimo Sf series damper actuator has a modulating control type. It is a spring return actuator with an emergency function for adjusting air dampers in ventilation and air conditioning systems in buildings. It has an adjustable U-clamp, which accepts round or square shafts. This actuator can be installed with a pre-tensioned spring. This product is controlled with a standard signal of DC 0V to 10 V and moves the damper to the operating position. It is overload proof, requires no limit switches. It requires 24VAC/VDC supply voltage.
