SQX32., SQX82. and SQX62. are three actuator products, suitable for VVF, VVG, VPF, VXF and VXG series valves. SQX32. and SQX82. operate at AC220V and AC24V respectively, and accept three-position control signals. SQX62. operates at AC24V and can receive DC0~10V and / or 0.1000Ω or DC4.20mA valve position signals. The functions can be enhanced by adding auxiliary switches and potentiometers. It can be directly installed with the valve body without the need for other setting tools. It has manual adjustment and position display functions. SQX82. and SQX62U are UL certified.
This manual provides detailed information for Siemens SQX32, SQX82 and SQX62 electric valve actuators, including technical parameters, wiring diagrams, and safety guidelines. It describes the three‑position control signals, optional flow‑characteristic settings, and UL‑certified versions.
Installation, calibration and maintenance procedures are explained step‑by‑step, with instructions for connecting power, performing stroke calibration, and servicing the actuator. Accessories such as auxiliary switches, potentiometers and heating elements are also covered. This manual is written in Chinese.

Connect AC 24 V power, press the S3 button, move the actuator to the 0 % (closed) position until the green LED flashes, then to the 100 % (open) position until the LED flashes again; the values are stored in the micro‑processor.
The actuators can provide up to 700 N of force.
Yes, both SQX82U and SQX62U models have UL certification.
The SQX32 actuator requires an AC 230 V power supply.
