Siemens SAS61.03 actuator
Siemens SAS61.03 electric motor actuator — precise control of valves in HVAC systems. The Siemens SAS61.03 actuator is a professional solution from the world leader in building automation for controlling regulating and shut-off seat valves in heating, ventilation, and air conditioning systems. If you need reliable automation that works without failures for years, this is the right choice. Application: The SAS61.03 actuator is used for seat valves with a stroke of 5.5 mm and is designed to control regulating or shut-off valves in heating and ventilation systems. Compatible with Siemens two- and three-way valves of the V..G44. and VVG55 series. Key features: The SAS61.03 electric motor actuator has a stroke of 5.5 mm and a positioning force of 400 N. Operating voltage AC/DC 24 V, control signal DC 0...10 V / DC 4...20 mA / 0...1000 Ohm, running time 30 seconds. Smart auto-adjustment — no unnecessary operations: During commissioning, the actuator determines the end positions of the valve and stores the stroke length value in internal memory. The device requires no adjustment and is ready for operation immediately after installation on the valve. Additionally, if an increase in force is detected in an intermediate position during operation, the actuator opens and closes the valve up to three times, ensuring removal of mechanical contaminants from the seat area. This extends the service life of the entire assembly. Ease of installation and operation: The actuator is mounted directly onto the valve — no adjustment required. Manual control, LED status indication, and position indicator are provided. Functionality can be expanded with additional switches. SAS series actuators require no maintenance. Why choose Siemens SAS61.03: • German quality from Siemens AG — one of the world's leading companies in automation technology.
