FLOGATE flap gates are self-regulating control gates designed to maintain water level differences by enabling unidirectional flow. When the upstream water level is higher, the gate opens to allow flow, when the downstream level rises, the gate shuts to prevent backflow. Manufactured from premium engineering-grade HDPE panels, FLOGATE requires no mechanical, electrical, or manual operation.
Available in both round and rectangular configurations, these gates can be installed as standalone units or integrated with WEIDA’s FLOLINE 3W, FLEXISS, or RSP pipes, and culverts to suit various applications.

Exceptionally Strong & Tough – Made from thick HDPE panels with robust stainless steel hinge joints, the reinforced design withstands hydrostatic pressure, strong flows, and debris impact.
Good Seal Performance – Features a proprietary PE seal system that is durable and provides a reliable, long-lasting seal.
UV Resistant – Contains carbon black additives that offer excellent protection against UV degradation during outdoor exposure.
Lightweight – HDPE is naturally lightweight, making transport, handling, and installation easier.
Fast Installation – Supplied pre-assembled onto FLOGATE pipes for quicker installation. Standalone gates come with flanges or clamps for easy attachment to existing structures.
Chemical Resistant – As an inert material, HDPE resists degradation from extreme pH levels in soil, sewage, and wastewater.
Abrasion Resistant – More resistant to wear than concrete or steel, HDPE maintains long-term flow efficiency without pitting or rusting.
