Siemens STA321.65L10 Thermal Actuator AC 230V On-Off

Innovative Automation in Precise Flow Control with ORFA Industrial Assurance

Siemens thermal actuator maximizes energy efficiency in heating, cooling, and air conditioning systems, providing a reliable solution for professional installations requiring precise flow control. With the STA321.65L10 model, Siemens expands its product range by combining thermal expansion technology with over a decade of European industrial automation expertise. This thermal actuator, stocked at ORFA Industrial, is designed for direct mounting on standard valves via M30×1.5 mm threaded connection. Thanks to its compact design, this thermal actuator operates reliably in cold and hot environments, independent of water and light exposure. With 230 Volt AC operating voltage, the thermal actuator connects directly to grid systems and consumes minimal electrical energy during the initial heating phase. Controlled by On-Off signals from the control electronics, thermal actuator movements regulate valve opening and closing with high precision. The spring system in the internal mechanism ensures that upon power loss, the valve automatically closes, enhancing system safety. With a positioning force of 125 Newtons, this thermal actuator easily drives medium-sized valves and is widely used in heating and cooling control panels. This thermal actuator requires no periodic maintenance and demonstrates robust construction against salt and humid environments, providing extended service life. Begin your Siemens thermal actuator application with ORFA Industrial to achieve thermal balance and energy savings in your heating and cooling systems.
