Belimo CQKB24-LL Actuator

For contractors demanding reliable zone control, the Belimo CQKB24-LL Actuator delivers robust performance. This 24V valve actuator is engineered as an electronic fail-safe, normally open (NO) unit, ensuring the fail-safe position is open. It's designed for direct mounting onto compatible valves, eliminating the need for additional tools or linkages, which streamlines installation on site. Operating with an On/Off control signal, the CQKB24-LL provides precise 90° rotation with a motor running time of 75 seconds and a fail-safe running time under 60 seconds. Its compact design and UL 2043 compliance make it suitable for air plenum applications, offering a dependable solution for various HVACR systems. With a low power consumption of 2.5W in operation and 0.5W in rest, this ZoneTight actuator is an efficient choice for critical zone control.
