Flanged Fully Enclosed Duckbill Check Valve
Prevents Backflow Inside the Pipe Line
Carbon Steel Fabricated Enclosure
The series DBMJ-F check valve effectively ensures mono-directional flow of slurries, sewerage, sludge and other hard to handle fluids. The valve consists of an elastomer duckbill type check valve inside a steel housing. This simple rugged design eliminates mechanical parts which can wear and jam in conventional check valves. They are available in a variety of elastomer compounds, with a carbon steel fabricated housing.
