Wiring Diagram

The basic wiring diagram refers to the right drawing. If other wiring is required, please contact us.


Introduction

1. The internal wiring is showed on the right side of the dashed line or inside the dashed line.

2. Limit switches in the diagram show that the valve is in the intermediate position.Torque switches show that the valve is not over torque.
