This valveis a special product ,and it is used for draining sewage .In many foreign countries,such as Spain , America,it is usually named as duckmouth-shaped valve .We are doing our best to make this valve more practical and more perfect . EPDM rubber duckbill valve can be matched with steel pipe ,cement pipe .At the same time ,they may be widely used on the coast,seasands,reservoirs,and so on.In order to dispose the sewage or to dredge the floods.
Some elastomers can hand corrosive or abrasive fluids such as raw sewage, sludge or slurries. The operating temperature of the valve is limited by the elastomer temperature capacity.
The rubberis all rubber reinforced. It consists in an elastomer sleeve flattened in one end. The Duckbill valve can only be opened when the forward flow lifts the sealing flattened side of the sleeve that, otherwise its natural position is to be closed.
EPDM rubber duckbill valve requires no external power sources and because there is not mechanism it doesn't require maintenance, therefore it can be more competitive than other valves used for the same function such as gate valves.
