Product Overview
The 4Nm/6Nm Modulating Standard Damper Actuators are designed for accurate control of air dampers in heating, ventilation, and air conditioning (HVAC) systems. With proportional control signals and real-time feedback, these actuators deliver precise airflow management, making them ideal for modern building automation and energy-efficient ventilation projects.
Engineered for medium to large dampers, these actuators provide a balance of power, durability, and advanced control-suitable for distributors, OEM brands, and ODM buyers seeking reliable actuator solutions.

Frequently Asked Questions (FAQ)
Q1: How long does delivery take for large actuator orders?
Standard orders are usually dispatched within 7–20 business days, depending on volume and customization.
Q2: What warranty do you provide for damper actuators?
We offer a 12–24 month warranty, covering manufacturing quality and defects.
Q3: What's the difference between "normally open" (NO) and "normally closed" (NC) motorized valves?
An NO valve allows flow when not powered, while an NC valve blocks flow when unpowered. Selection depends on safety requirements and system design.
Q4: How do I choose the right actuator or valve for my project?
Consider torque rating, damper size, control type (On/Off, floating, or modulating), and voltage. Our technical team provides free selection guidance.
Q5: Do your products support proportional control (0–10V, 4–20mA)?
Yes. These actuators are designed with proportional input and feedback signals for accurate and energy-efficient regulation.
