■ Overview

The ZDRQR electric O-type three-way ball valve consists of an electric actuator and a three-way O-type ball valve. By changing the relative position between the core and the pipeline, different combinations of fluid control can be implemented for the three pipelines.

This product uses 220V single-phase AC power as the power source, receives switch signals from the control system, and drives a reversible single-phase gear reducer through single-phase power switching, enabling the ball valve to switch the pipeline according to the specified requirements.

A T-shaped tee can connect three orthogonal pipelines to each other, either by merging or merging, or by connecting two of them and cutting off the other pipeline.

The L-shaped tee can only connect two mutually orthogonal pipes or switch directions, that is, it plays a role in distribution.
