How It Works

Understanding the engineering principles behind our flap gate valve technology

1

Flow Direction

Water flows in the designated direction, opening the flap gate through hydraulic pressure and allowing smooth passage.

2

Backflow Prevention

When reverse pressure occurs, the flap gate automatically closes, creating a tight seal to prevent backflow.

3

Self-Cleaning Action

The flap's movement creates a self-cleaning action, preventing debris accumulation and maintaining optimal performance.
