Series Description
The Belimo NKQ Series actuators are electronic, fail safe, fast acting actuators. They are designed to deliver a 4 to 10 second (4 second is standard) fail safe return. They are not spring return, but rather they are driven by a super capacitor which allows a very fast return to the normal or fail safe position desired. The basic models come in both ON/OFF and 2-10VDC options. Auxillary switches and feedback options are available on the NKQB24-1 model. The NKQB24-SR comes with a feedback of 2-10 VDC standard and the auxillary switch is an optional add-on. For more customized control, the NKQx-MFT models can be custom ordered based on the options available.
