Description
The Belimo NKQB24-1 is an electromechanical controller for HVAC systems. It is an on/off damper actuator, indicating that it receives a signal to turn on or off and governs the orientation of dampers, valves, and other air circulation components of the system. The NKQB24-1 is a normally-closed spring-return actuator, which means it utilises a spring that returns to the closed state when electricity is withdrawn. This secure architecture guarantees that the system stays shut in the event of an electrical outage, possibly preventing the propagation of fire or smoke. The Belimo NKQB24-1 operates on 24 volts of oscillating or direct voltage electricity and has a torque rating of 53 inch-pounds.
