SAS61.03 (400 N, 5.5 mm, AC/DC 24V)
Siemens actuator series for automatic, precise modulating and on/off control of linear valves, small valves, and zones in HVAC systems.
Siemens SAS, SFA, and SUA electric actuator series are engineered for comprehensive valve control in building automation and HVAC systems. The SAS61.03 linear actuator operates on AC/DC 24V, providing a 400 N positioning force and high-precision modulating control for linear valves. The SFA21/18 and SUA21/3 models operate directly on AC 230V, delivering reliable on/off control and rapid response for fan-coils, manifolds, and zone valves.
