Key Features
- Wide input voltage range: 100–240V AC for versatile system integration
- 75-second runtime for smooth, controlled actuation
- Normally Open (NO) / Fail-Open (FO) operation for safe default positioning on power loss
- Designed for HVAC zone control applications
- Compact, robust construction for reliable long-term performance
- Manufactured by Belimo, a global leader in actuator and valve technology
Fail-Safe Operation
The CQKBUP-LL features a Normally Open, Fail-Open (NO/FO) configuration, meaning the actuator returns to the open position upon loss of power or control signal. This fail-safe design is critical in applications where maintaining airflow or fluid flow during a power interruption is essential for system safety and occupant comfort.
Application
Ideal for use in commercial and residential HVAC zoning systems, the CQKBUP-LL integrates seamlessly with zone control boards, building automation systems, and hydronic or air-side zone valve assemblies. Its wide voltage compatibility makes it suitable for both North American and international installations.
