SA905-V 0-10V Modulating Electric Thermal Actuator delivers precise flow control with 0-10V proportional modulation, enabling continuous valve positioning and stepless output for optimized temperature regulation. As part of the SA Series Electric Thermal Actuators, it features high-precision stepper motor technology, real-time control adaptation, and Bluetooth flow limit setting via mobile App. The M30×1.5 interface fits standard manifolds without adapters, while the IP54-rated sealed housing ensures reliable performance in demanding environments.

Supports standard 0-10V proportional control signals for continuous, stepless valve modulation. This enables precise flow regulation, accurate temperature control, and enhanced hydronic system performance across all load conditions.
Advanced stepper motor drive delivers faster response times, more accurate valve positioning, and superior operational stability compared to conventional thermal actuators — ensuring consistent system performance in dynamic HVAC environments.
By continuously matching flow output to actual system demand, the SA905-V eliminates excess circulation and prevents over-heating. This reduces unnecessary energy consumption and lowers heating costs without compromising comfort.
Continuously responds to control system signals and adjusts valve position in real time. This dynamic adaptation ensures stable indoor temperatures and optimal system efficiency under varying load conditions.
Built-in Bluetooth connectivity allows installers and service engineers to set flow limits, configure parameters, and monitor actuator status directly via mobile App — without opening electrical panels or using external gateways.
Sealed IP54-rated housing provides enhanced protection against dust ingress and water splashes. The corrosion-resistant construction ensures reliable performance in manifold cabinets, plant rooms, and mechanical spaces with high humidity or exposure.
