Siemens Building Technology SAS81.03U 3-POS Electromotoric NSR Valve Actuator 24V

The Siemens SAS81.03U Valve Actuator was designed to control HVAC systems precisely. The actuator operates at 24V and has a 5.5 mm stroke with a 3 position floating control signal type for precise valve position adjustment. In temperatures from -5C to 55C temperature, with a relative humidity up to 95%, it would be adaptable to many different environments, and it is designed for heating, ventilation, and air conditioning systems, to improve system performance using reliable and accurate valve control. That implies higher temperature control more energy efficiency and the same comfort over the HVAC system.
