Siemens STA321.65L10 Thermal Actuator 230V On-Off
Precise flow control with automatic safety for efficient heating and cooling systems.
Siemens STA321.65L10 Thermal Actuator 230V On-Off is a reliable automation component that enhances energy savings in heating and cooling systems. In addition, it operates on the thermal expansion principle and connects directly to the mains with a 230 V AC supply. Furthermore, it delivers precise flow balancing in central heating panels and air conditioning units.
The thermal actuator provides a 6.5 mm stroke for accurate valve opening and closing. Moreover, its 125 N positioning force drives medium-sized valves and ensures fast system response. In addition, the NC (normally closed) design automatically closes the valve during power failure, increasing installation safety. Therefore, it requires no periodic maintenance and offers IP54 protection against salt and moisture.
