SQX32, SQX82, SQX62 are 3 types of electric valve actuators, which can be used for VVF, VVG, VPF, VXF, VXG series of valve actuators, with a driving stroke of 20mm. Suitable for -15~+50℃ ambient temperature, valve internal medium temperature -25~+140℃.
This manual provides detailed information on the Siemens SQX32, SQX82 and SQX62 electric valve actuators, including their mechanical features, electrical connections, and optional accessories. It covers the three‑position control signals for the SQX32 and SQX82 models and the DC 0‑10 V, 0‑1000 Ω or 4‑20 mA signals for the SQX62 series.
The document explains how to perform travel calibration, install auxiliary switches and heating elements, and conduct safe maintenance. Technical data such as stroke, force, power consumption, operating temperature range and IP rating are listed for quick reference. This manual is written in Chinese.

Connect the AC 24 V power, press the S3 button, the actuator moves to the 0 % position (LED flashes), then to 100 % (LED flashes) and stores the values in the micro‑processor.
The SQX82…U and SQX62U versions are UL certified.
The actuator can develop up to 700 N of force.
The SQX62 series accepts DC 0‑10 V, 0‑1000 Ω or 4‑20 mA signals (or any combination).
