♦Special Customized 
At the same time, we provide customizing service, if all of our products cannot meet your requests, we also can specially customize the products for you as per your samples, drawings, etc. 

 

The main advantage of duckbill valves over other types of oneway valves is that duckbill valves are
self contained i.e. the critical sealing function is an integral part of the one piece elastomeric
component as opposed to valves where a sealing element has to engage with a smooth seat surface to form a seal.


Therefore duckbill valves are easily incorporated and assembled into a wide varietyof devices without the hassle or problems associated with the surface finish quality of mating seats and /or complex assemble process.
