Smart Flow Control for Modern Water Infrastructure

A practical overview of gates, weirs, actuators and flushing equipment used in water infrastructure.

Flow control equipment from the original G-LINK article

Flow regulation decides everything. When gates, weirs and actuators perform well, the entire system feels stable. When they do not, operators feel it immediately.

Here is a look at key gate and mechanism solutions from our China manufacturing partners. Each design focuses on durability, sealing stability and engineering reliability.
