What is the pressure resistance of the duckbill valve?

The duckbill valve is made of ductile neoprene and synthetic fiber through special production process, and looks similar to the shape of a duck's beak, hence the name duckbill valve. When the internal structure does not have working pressure, the inlet and outlet of the duckbill valve close together under the action of its own ductility. The function of the gate valve of the duckbill valve is to allow the material to flow in one direction only, and to block the directional flow. Usually this type of gate valve is fully automatic operation, the piston valve opens under the action of the working pressure of the liquid moving in one orientation; when the liquid moves in the reverse direction, the self overlapping piston valve by the working pressure of the liquid and the piston valve efficacy in the high pressure gate valve, and thus disconnects the mobility.

Duckbill valve is generally installed in large cities on the surface of the sewage pipeline system software at the intersection of branch routes, can be based on its own ductility self-sealing basic principle, can reasonably prevent the tide water line is high, flood backflow into the surface of large cities, sewage treatment stations and other areas, reasonable to ensure the reliable operation of such critical areas. Duckbill valve can not only ensure a reasonable check for the liquid, for the smell of liquid as well as can establish a better smell sealing effectiveness, further improve the actual effect of check, reasonably ensure a better urban natural environment. And duckbill valve relative to other metal materials duckbill valve in the sewage treatment process if a relatively large particles of residue can be reasonable circulation, to prevent the blockage of residue caused by hanging open condition. Whether from the selection of raw materials or from the duckbill valve processing technology, we have a unique experience and planning solutions to ensure the quality of each rubber joint. We can customize our products according to customer satisfaction.
