Onyx DBS Slip-On Duckbill Check Valve

Prevents Backflow at the End of a Pipe

The series DBS rubber check valve effectively ensures mono-directional flow of slurries, sewerage, sludge and other hard to handle fluids. The valve consists of an elastomer duckbill with a slip-on connection. This simple rugged design eliminates the mechanical parts which can wear and jam in conventional check valves.
