Belimo CQKB24-LL Spring Return Damper Actuator Second Timing - 24V 75

The Belimo CQKB24-LL is a 24V spring return damper actuator designed for precise HVAC zone control applications. This normally open, fail-safe open (NO/FO) actuator features a 75-second timing motor for controlled, smooth operation in commercial and industrial building automation systems.

Key Features:

• 24 VAC/VDC power supply for versatile installation compatibility
• 75-second full stroke timing provides gradual damper positioning
• Spring return design ensures fail-safe open operation during power loss
• Normally open configuration for safety-critical applications
• Compact, durable housing suitable for HVAC zone control
• Reliable Swiss-engineered construction from industry-leading Belimo

This actuator is ideal for controlling zone dampers in VAV systems, smoke evacuation applications, and other scenarios where fail-safe open operation is required. The spring return mechanism automatically returns the damper to the open position upon power failure, ensuring proper airflow and system safety.
