Belimo ZONE120NO-S Actuator

For reliable zone control in your HVAC systems, consider the Belimo ZONE120NO-S actuator. This robust 120V spring return actuator is engineered for precise on/off operation, ensuring your systems maintain optimal performance. As a normally open zone valve actuator, it defaults to an open position, providing fail-safe functionality crucial for critical applications. It integrates seamlessly into various setups, requiring an AC 120 V nominal voltage and drawing 6.5 W running power, with a 7 VA transformer sizing. The unit features a 90° angle of rotation and a rapid fail-safe running time of less than 5 seconds. Equipped with a single SPST auxiliary switch actuator rated for 5 A resistive at 120 V, it offers additional control and feedback capabilities. Its NEMA 1 / UL Enclosure Type 1 protection and galvanized steel housing ensure durability in typical mechanical room environments, meeting cULus requirements without needing an electrical ground connection. This actuator is a solid choice for dependable HVAC zone control.

• Key Benefits:
  • Reliable Fail-Safe Operation: Spring return mechanism ensures the valve defaults to a normally open position upon power loss, maintaining system integrity.
  • Integrated Auxiliary Switch: Provides a single SPST contact for system feedback or interlocking with other controls, enhancing operational flexibility.
