The electrothermal actuator STA121.65 from Siemens is designed for precise control of radiator, small, and zone valves, as well as PICV. This model is maintenance-free and constructed for long-term and quiet operation, making it ideal for technical applications where reliability and minimal maintenance are important. It operates with an AC/DC 24 V supply voltage and is equipped with several features that facilitate installation and operation.

Application

Control of terminal units on the water side, heating, and cooling zones
Combination with Siemens radiator valves (VDN, VEN, VPD, VPE....)
Can also be combined with radiator valves from other manufacturers (Heimeier, Cazzaniga, Oventrop M30 x 1.5, Honeywell-Braukmann, and MNG - without the need for an adapter)
The actuator position display is readable from a 360° angle, which facilitates monitoring and maintenance.
