Flap Gates

Flap gates are critical for backflow prevention in stormwater, tidal, and drainage systems. Whipps manufactures stainless steel flap gates designed to provide dependable one-way flow control, preventing reverse flows that could lead to flooding, contamination, or damage to infrastructure.
A flap gate operates by swinging open under forward water pressure, allowing flow to pass through. When pressure reverses, the gate closes automatically, sealing against its frame to prevent backflow. This passive design requires no external power or manual operation, making flap gates highly efficient and low-maintenance.
Whipps flap gates are fabricated entirely from stainless steel, ensuring long service life and resistance to corrosion, even in challenging environments such as saltwater or wastewater systems. Each flap gate is custom-built to match site conditions, with options for round, square, or rectangular openings. The precision fit and robust construction provide a reliable seal and consistent operation across a wide range of hydraulic conditions.
Engineers and municipalities rely on Whipps flap gates to protect infrastructure and communities from flooding and contamination risks. By combining high-quality materials with expert engineering, Whipps delivers flap gates that provide peace of mind and decades of service with minimal upkeep.
