APPLICATION OVERVIEW
The NAV series Electric Valve Actuator features a complete range from 1000N to 3000N actuating force.
They are use with the globe valve to regulate the flow of water or Steam. The Actuator can be ordered with NENUTEC Valve NVCS or NVCF series valves and NTC controller for a complete HVAC solution.
FAQ
Q1: How should damper actuators be installed and maintained?
Installation is simple, with universal mounting brackets and clear wiring diagrams provided. Minimal maintenance is required-just periodic inspection to ensure smooth damper operation.
Q2:How do I troubleshoot a damper actuator that is not working?
Common steps include checking power supply, control signal input, wiring connections, and damper movement. Our technical team provides full support and manuals for troubleshooting.
Q3. Can I request samples before placing a large order?
Yes. We welcome international buyers to test samples of our damper actuators before bulk purchasing.
Q4. Are your damper actuators compatible with different control signals?
Yes. Our actuators support ON/OFF, floating point, modulating control (0–10V or 2–10V DC signals), making them suitable for most HVAC and building automation systems.
