Rubber duckbill check valve description

The duckbill valve is made of elastic neoprene and nylon cord fabric through special processing. It has the characteristics of high elasticity. In the case of no internal pressure, the outlet of the duckbill is closed under the action of its own elasticity, which can prevent the external liquid from flowing back into the pipeline; it needs to be discharged When it is liquid, as the internal pressure gradually increases, the outlet of the duckbill gradually increases, so that the liquid can be discharged at a high flow

Rubber duckbill check valves can be divided into three categories according to the connection method:

NO.1 Clamp connection rubber check valve
NO.2 Flange connection rubber check valve
NO.3 Built-in rubber check valve.
