In detail
HDPE Flap Gate
The HDPE Flap Gate is designed for backflow prevention and flood control in drainage, riverine, coastal, and industrial systems. Its self-acting, one-way mechanism allows efficient discharge while automatically preventing reverse flow during high tides or flooding.
Made from high-density polyethylene (HDPE), it offers excellent corrosion and impact resistance, ensuring long service life, low maintenance, and reliable operation without external power.
