In foreign countries such as Spain or America,it is usually named as rubber valve.Rubber duckbill valve can be matched with straight pipeline,flange pipe. At the same time, they may be widely used on the coast, sea-sands, reservoirs,and so on in order to dispose the sewage or to dredge the floods.Indeed ,it is environmentally-friendly valve.
According to the different media, the duckbill valve is made of also different material. Natural rubber has good elasticity, good air tightness, great elongation, great tensile strength, good processing technology performance, which is suitable for grinding particles and weak chemical liquid. Chloroprene Rubber has excellent resistance to aging properties and excellent resistance to corrosion resistance and excellent oil resistance, solvent resistance, suitable for oil, Middle strength chemical medicine, ozone and fluorocarbon. NBR is suitable for all kinds of fluorocarbon chemicals in strength, with temperature under 200 DEG C. Fluorine rubber is suitable for ozone, oil, chemical solvents, halogen carbon and oxygen.
Rubber duckbill valve is produced by integrated molding technology. Full rubber design of the valve body will not cause the sedimentation and stuck phenomenon, reduced maintenance costs, and allowing the solid particles to pass through smoothly.
