Overview
The Spring-return Damper Actuator (230V ON/OFF, 10Nm/15Nm/20Nm) is a high-performance actuator engineered for air control dampers in HVAC systems. Designed for universal AC 100–240V power supply, it offers stable operation, precise torque output, and a fail-safe spring-return function that ensures damper safety during power interruptions.
Thanks to its robust design, long service life, and versatile mounting options, this actuator is ideal for modern building automation and industrial HVAC projects.
Highlights & Advantages
● Multiple Torque Choices – Available in 10Nm, 15Nm, and 20Nm to suit different damper sizes.
● Wide Voltage Range – Works with AC 100–240V (85–265V tolerance), compatible with international standards.
● Reliable ON/OFF Function – Simple yet effective control for common HVAC applications.
● Spring-return Safety Feature – Restores damper to default position if power is lost.
● Durable & Compact – Built for heavy-duty HVAC usage with reduced maintenance needs.
● Optional Auxiliary Switches – Add 2 SPDT switches for extended control flexibility.

FAQ
Q1: Do you provide both 2-way and 3-way motorized valves?
Yes, we manufacture both. A 2-way valve controls flow in one direction, while a 3-way valve allows mixing or diverting between two outlets.
Q2: What materials are your motorized valves made from?
We supply options in brass, stainless steel, and PVC, depending on the fluid medium and application environment.
Q3: Are these actuators and valves suitable for HVAC and industrial automation?
Absolutely. They are widely used in HVAC heating & cooling, water supply systems, wastewater treatment, irrigation, and industrial automation projects.
Q4: Do your products meet international certifications?
Yes. Our actuators and valves comply with CE, RoHS, and ISO standards, ensuring safety and performance.
Q5: Can these be integrated with building automation systems (BAS/BMS)?
Yes. Our actuators and motorized valves are compatible with BMS, BAS, Modbus, KNX, and other smart building protocols.
