Flange Type duckbill check valve
Flange type Rubber Duckbill Valves, widely used in the demanding applications of many industries, are precision-molded, one-piece elastomeric valves that provide reliable backflow prevention at low pressure differentials. Rubber Duckbill valves allow free flow with positive differential pressure.
Normally Open one-way check valves
Prevents backflow leakage when minimal backpressure is applied
Can be installed easily into hole and sealed by compressing flange
