Product Features

ΔT Automatic Balancing Control.

Advanced ΔT control algorithms continuously monitor the temperature difference between supply and return water circuits and automatically adjust valve positions to maintain dynamic flow balancing. This effectively eliminates uneven heating, overheating, and insufficient heat distribution — ensuring consistent comfort across all zones.
Precision Stepper Motor Technology.

Powered by a high-precision stepper motor, the actuator provides faster response times, more accurate valve positioning, and longer service life compared to conventional thermal actuators, making it ideal for high-efficiency heating systems where precise flow control is critical.
Bluetooth App Remote Diagnostics.

The integrated Bluetooth App enables wireless commissioning, parameter configuration, real-time monitoring, operational data analysis, and fault diagnostics without requiring an additional gateway, significantly reducing installation and maintenance costs for facility teams.

Dynamic Flow Control Optimization.

By continuously optimizing system flow rates, the actuator minimizes over-circulation and unnecessary energy consumption, improving overall system efficiency while maintaining superior thermal comfort across all conditioned spaces.
IP54 Protection Design.

Featuring an IP54-rated enclosure, the actuator offers reliable protection against dust and water splashes, ensuring stable and long-lasting performance in demanding installation environments such as hydronic manifolds and plant rooms.
Universal Compatibility.

Designed with a standard M30×1.5 connection interface, the SA905-T is compatible with most mainstream manifolds and valve bodies, making it suitable for both new installations and energy retrofit projects without custom adapters.
