Coldwell-Wilcox - Flexible Flap Gates
Flexible flap gates are excellent for water and wastewater applications. Suited for gravity flow by opening under very low unseating head. Also suited for pump discharge and withstanding the pump discharge slamming action. A flexible flap gate usually consists of a stainless steel frame, minimum 1' thick reinforced flexible neoprene cover, flexible cover hinge and neoprene lip seal seat. The resilient seat minimizes the leakage.
