2) installation dimensions in Jiangsu the Blue valve, Nanjing water beauty of its own size, the size of different national standards, but there are likely to prevail in American Red valve or Spain screw.


 

Rubber Duckbill Valve Directions:

 

1) Open pressure: 0.003MPa, equivalent to a basin of water.
Under normal circumstances, the duckbill valve can normally 3 meters in the underwater work, but this height is, counting from the bottom of the duckbill valve, plus special apparatus, can reach 10 meters underwater.

2) Service Life: the design life of two years, but in general, at room temperature, and the climate is bad, you can use five years, even as long as 10 years, but the proposed one-for five years to prevent aging.

The advantages are specially marked in comparison with traditional flap valve:

 

 

1. Open and close automatically in security and reliability according to hydraulic difference without noise and in no need of operator and maintenance;

 

2. Positive start has little water resistance and start –up pressure and the flow can be adjusted naturally according to hydraulic pressure.

 

3. Reserve cut-off has good seal without leakage to prevent from flowing backwards. The back pressure is higher and the effect is barrier;

 

4. Anticorrosion, aging resistance, deformation resistance, strong adapt-ability and long use life;  

 

5. Wide size scope, nominal diameter of DN50-DN3000.
