Circular Flap Gates

Fontaine-Aquanox SERIES 60 have been designed with contractors in mind and are very easy to install with the use of the thick wall gasket and standardized components. 

Many different mounting options are offered to match the specific needs of each application.

SERIES 60 flap gate is the simplest way to prevent flows of water from returning back into pipes or openings. 

The gate design is such that whatever the size, a small flow will open the gate in negative pressure but it will remain watertight for positive pressure. 

On larger sizes, the flap can be adjusted to open under a specific head of water since its adjustable hinges can modify the force needed to push the flap
