Belimo CQKB24-SR-LL N/O Modulating Valve Actuator 2-10 VDC or 4-20mA 24V

The Belimo CQKB24-SR-LL N/O Valve Actuator is used in HVAC systems for accurate control. It makes valve positioning automatic to control the flow of fluids in the system. It has a modulating control type and can be controlled in proportion to the input signals of 2-10 VDC or 4-20mA with a power supply of 24V. The normally open contacts indicate that the valve is open provided the actuator is without power. It is fitted in HVAC products such as AHU and FCU to maintain a correct temperature and airflow. Advantages are increased energy management efficiency due to better flow control, and better conditions control to provide comfort and stable system control.
