Advantages of Non Fail-safe Damper Actuator

High Energy Efficiency

Actuators to minimise energy consumption while delivering consistent torque output.

 

Compact, Versatile Design

Available in a range of torque ratings, shaft configurations, and control options for easy integration into new or retrofit projects.

 

Quiet Operation

Designed for smooth and silent movement, perfect for noise-sensitive environments.

 

Long Service Life

Robust components and quality testing ensure long-term reliability, reducing maintenance requirements.

 

Applications of Non Fail-safe Damper Actuator
 

Air Handling Units (AHUs)

Regulating airflow through dampers without requiring automatic fail-safe repositioning.

Zone Control in Ventilation Systems

Holding the last position in case of a power outage, avoiding unnecessary operational resets.

Heating and Cooling Loops

Controlling valves in secondary circuits where immediate fail-safe action is not essential.

Laboratories and Commercial Offices

Maintaining airflow patterns to avoid disruption during temporary power interruptions.

 

 

Precautions for Using Non Fail-safe Damper Actuator

》Periodically inspect the actuator for signs of wear, corrosion, leakage or damage. Check all mechanical linkages, seals, and electrical connections.


》Lubricate moving parts in accordance with the manufacturer’s recommendations, depending on the type and use of the actuator.


》Calibrate the actuator periodically to ensure that it responds accurately to control signals. This may include checking feedback sensors and calibration.


》Periodically check and replace filters and ensure that fluids or air are clean and that hydraulic and pneumatic actuators are properly pressurised.


》If the actuator has fail-safe or emergency features, test it periodically to ensure proper function.

FAQ

 

Q: Do you support ODM/OEM projects?

A: Absolutely. We provide customized torque ranges, wiring, housing, branding, and packaging to meet partner requirements.

Q: What certifications do your products have?

A: CE, RoHS, ISO certified. UL-certified models are also available on request.

Q: What is the difference between NO (Normally Open) and NC (Normally Closed) configurations in valves?

A: An NO valve allows flow when not energized, while an NC valve blocks flow when not energized. The choice depends on the control system and safety requirements.

Q: Can I order samples for evaluation?

A: Yes, we supply samples to help customers test performance before large-scale orders.

Q: What warranty is provided for these damper actuators?

A: We offer a 12–24 month warranty, covering any manufacturing defects.

Q: How long do your actuators typically last?

A: Tested for durability, our actuators deliver a service life of 100,000+ cycles, depending on environmental conditions.
