Siemens GDB / GLB Rotary Actuator for Ball Valves 5–10 Nm
Siemens GDB / GLB Rotary Actuator for Ball Valves 5–10 Nm
The Siemens GDB / GLB series are electromotive rotary actuators that operate ball valves with a 90° rotation. GDB models provide 5 Nm and GLB models 10 Nm of torque; they have no spring-return function and the running time is 150 seconds.
Models with code 341 provide 2/3-position control at AC 230 V, while models with code 161 provide DC 0…10 V modulating control at AC/DC 24 V. The GLB341.9E is listed under two different Siemens order codes. Compatible ball valve series are listed below.

This list is verified compatibility information based on Siemens product matching data; it is not a list of similar-product suggestions. You can make the final selection with our engineering team based on your project conditions (differential pressure, stroke, control signal).
Selection and installation notes
- The actuator's actuating force and stroke must match the close-off pressure and stroke of the valve it is fitted to.
- The supply voltage and control signal (3-position, DC 0…10 V or on/off) must match the controller output.
- Refer to the datasheet for mounting position and ambient temperature limits.
