This document introduces the functions and characteristics of the electric actuator GLB131.9E/GLB331.9E/GLB161.9E, including the working voltage, control mode, position indication mode, and manual adjustment mode.
The GLB series electric actuators are designed for two‑way ball valves (DN15‑DN50) and support either three‑position control or analog (0‑10 V) control. They are supplied with a 0.9 m power cable and can operate from AC 24 V or AC 230 V depending on the model. The direction of rotation (clockwise or counter‑clockwise) is set by a dip‑switch configuration.
The document gives an overview of the product, key technical parameters, wiring diagrams for both three‑position and analog control, and safety/installation notes. Detailed installation and commissioning instructions are referenced to the technical basic document Z4634en. This manual is written in Chinese.
