Does the unclosed punch on the duckbill valve of the breast pump affect suction?

The duckbill valve is an important component of a breast pump, located inside the valve of the breast pump. Its main function is to prevent milk from flowing back and ensure the normal operation of the breast pump. When the breast pump is working, the duckbill valve will tightly adhere to the valve, forming a sealed space that allows milk to flow into the bottle through the breast pump's tubing without flowing back into the tubing. Therefore, the duckbill valve is crucial for the proper use of a breast pump. Generally, the material of the duckbill valve needs to have a certain degree of softness and elasticity to ensure the sealing effect, and it should be easy to clean and replace.


If the duckbill valve of the breast pump has cracks or other damages, it will affect the normal operation and suction of the breast pump. The main function of the duckbill valve is to prevent milk backflow and ensure the normal operation of the breast pump. If there are cracks in the duckbill valve, it will cause poor sealing, and the milk will flow back into the tube of the breast pump, thereby affecting the suction of the breast pump. Therefore, once cracks or other damages are found in the duckbill valve, it should be replaced in time to ensure the normal operation and suction of the breast pump.
