More details of Rubber Duckbill Check Valve:
The rubber lined duckbill check valves effectively ensures monodirectional
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.
Rubber Duckbill check valve characters:
1. Compact & easy to install
2. Absorbs movement in all directions
3. Reduces mechanical noises
4. Compensates for misalignment
5. Relieves strain on the piping system
6. Does not require gaskets
The advantage is specially marked in comparison with traditional flap valve.
Open and close automatically in security and reliability according to hydraulic difference without noise and in no need of operator and maintenance. Positive start has little water resistance and start-up pressure and the flow can be adjust naturally according to hydraulic pressure. Reserve cut-off has good seal without leakage to prevent from flowing backward. The back pressure is higher and the effect is better. Anticorrosion, prevent aging, strong applicability and long use life. Wide size scope, nominal diameter of DN20-2400.
