In the era of smart buildings, temperature control is no longer a simple on-off switch but a perfect balance of precision, stability, and energy efficiency. The Hengsen DFQ-S Series Electric Valve Actuators redefine flow regulation with innovative technology, infusing modern buildings with a "smarter" intelligence core.
In complex fluid control scenarios such as central air conditioning and heating systems, precise flow regulation is key to achieving both a comfortable environment and high energy efficiency. Designed specifically for 2-way/3-way valves, the Hengsen DFQ-S Series Electric Valve Actuators, with their industry-leading control performance and flexible adaptability, are the ideal choice for applications ranging from room temperature control to building-wide automation.
Four Core Advantages, Redefining Actuator Standards
1.Precision Control with Near-Zero Error
Equipped with a brushless DC motor, the actuator maintains constant speed even under varying loads, fundamentally eliminating flow fluctuations. A seamless connection structure eliminates mechanical gaps, enabling high-precision adjustment with near-zero error and ensuring long-term stable operation.
2.Five Adjustable Speed Settings for Faster Response
With five adjustable speed settings ranging from 0.3 to 0.7 mm/s, the actuator easily adapts to different system response needs. Whether for rapid temperature adjustment or smooth operation, it ensures precise matching, significantly enhancing system control efficiency.
3.Intelligent Integration for Seamless Building Management
An optional RS485 communication interface supports the Modbus protocol, enabling seamless integration with Building Automation Systems (BAS) and smart management platforms. This allows for remote monitoring and centralized scheduling, empowering the upgrade to smart buildings.
4.Triple-Mode Operation + LED Status Display for Easy Maintenance
Featuring mechanical manual, button manual, and automatic modes, the actuator allows free switching to meet debugging, emergency, and daily operational needs. Paired with an intuitive LED indicator that displays operational and fault status in real time, it greatly reduces maintenance difficulty and enhances system reliability.
