Duckbill Check Valves for Industrial Applications

  • Duckbill Check Valves

Cla-Val Pacific Series DB Duckbill Check Valves are a flexible sleeve design made of quality fabric-reinforced elastomer materials for maximum resistance to corrosion and wear caused by continuous operation with abrasive slurries, sludge, or effluent.  The flexible sleeve provides maximum flow with a minimum pressure drop across the valve at all times. 

The "duckbill" concept check valve has been in use for over 100 years in waterworks and commonly accepted for use in industrial process piping systems and in waste and storm water or sewer piping systems.
