Siemens SQL341 Butterfly Valve Actuator 100–400 Nm, 230 V
Siemens SQL341 Butterfly Valve Actuator 100–400 Nm, 230 V
The Siemens SQL series are IP67-protected rotary actuators that operate butterfly valves with a 90° rotation. The 100 Nm (SQL341E100) and 400 Nm (SQL341E400) models operate at AC 230 V with 3-position control.
Used with VFL41 / VFW41 butterfly valves in chillers, cooling towers and main distribution lines.

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.
