Duckbill check 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. Duckbill check valves allow free flow with positive differential pressure. With negative differential pressure, backflow is checked. Pressure drop across the valve is a feature unique to duckbill check valves. They can be designed to operate in a few millimeters (inches) of water to several hundred kpa (psi), depending on valve size, geometry and compound characteristics. Duckbill check valves are also designed to start functioning at specific opening and closing pressure ranges, depending on your specifications.
•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
Duckbill check valve features:
Reliable backflow prevention
100% elastomeric construction eliminates maintenance
Will not corrode, warp or freeze open or shut
1”-2” cracking pressure, low head loss
Curved bill enhances sealing around debris
Custom built for each application based on pressure and flow conditions
Available in diameters from 1/2" (12mm) to 96” (2400mm)
