Expansion Duckbill Valve is a new water supply and drainage valve with full Rubber structure. It has duck-mouthed appearance and functions of positive flow-in and reverse nonreturn. It's manufactured according to force analysis andCalculation, we use different designing mechanisms and choice different rubberFormula to resolve different engineering status.
The products used widely in cityPlanning, water conservancy, industry and sewage disposal etc. This kind of valve pays special attention to the direction of media flow, media should be the normal flow direction and the direction of the arrow indicated on the valve bodyIs consistent, otherwise you will cut off the normal flow of media.
At the end of theValve should be installed in the pump suction pipe at the bottom. The main advantage of duckbill valve over other types of one-way valves is that duckbillValves are self contained as opposed to valves where a sealing element has to engageWith a smooth seat surface to form a seal.
