The Siemens SUA21.3 is an electromotive actuator designed for zone valves in heating, ventilation, and air conditioning (HVAC) systems. It is compatible with Siemens VVI46, VXI46, VPI46, and VPP46 valves and is primarily used for the water-based control of hot and cold water. The actuator operates with an AC 230 V voltage and provides 2-position control (on/off) with a positioning force of 170 N. The unit comes with an integrated 0.8 m cable and offers LED indication for actuator motion. Its design allows for direct mounting using an M30 x 1.5 union nut, with no tools required.
