Breast Pump Valves are also known as Breast Pump Duckbill Valve, Breast Pump Replacement Valve, Breast Pump Membrane, Milk Valve for Manual Breast Pump, is the Liquid Silicone Valve that used for electric milk pump and manual milk pump, Silicone Duckbill Valve is widely used in breast pump device kits by many baby care company like Ameda, medela duckbill valve, spectra duckbill valve etc, and produced by LSR Injection Molding by FDA Food Grade Liquid Silicone material.
Breast Pump Duckbill Valves
Breast Pump Duckbill Valve & One Way Check Valve, are also known as Breast Pump Valves, Breast Pump Replacement Check Valve, which valve designs take full advantage of one way check valve with duck shaped bills & lips in aim to allow air or fluid liquid forward flow and also prevent backflow.
Breast Pump Duckbill Valves, is made from liquid silicone rubber & LSR, which don't like compression modled HTV (solid )silicone, more safe for baby care. Liquid silicone rubber which need intersive distributive mixing and also need cold runner systems in aim to maintain liquid silicone materials at a lower temperature before injected into heat cavities & chambers for vulcanization. Solid Silicone duckbill valves is easy to polluted by workers when production, and also not fully cured (some hazardous substance still stay in molded silicone even secondary vulcanization by even)

Liquid Silicone Breast Pump Duckbill Injection Manufacturing Process
Why Choose LSR Liquid Silicone material for Breast Pump Valves?
In comparison to other elastomers, LSR Liquid Silicone Duckbill valve is resistant to bacteria growth and will not stain or corrode other materials. Liquid Silicone Breast Pump Duckbill Check Valves can meet all food grade requirement & certifications like UPS Class VI, FDA 21 CFR 177.2600, BfR XV etc.
Liquid Silicone Valves are ideal for direct and indirect food contact because of their inorganic nature. They are heat resistant, easy to clean and satisfy all current food legislation.
LSR Breast Pump Valve's material Liquid Silicone Rubber & LSR is a two-part platinum-cured silicone, which is a high-purity and non toxic materials with lower compression set, lower outgassing, high heat resistance (working temperature: -40oC ~ 230oC), good tensile strength and tear resistace.
For the LSR Valve made by LSR injection molding, the surface of the product is completely frosted, transparent, no flash, no thorns, the whole surface is smooth and beautiful.
When to Replace Breast Pump Valves?
When your breast pump’s suction has decreased, there are two things you should check first: your pump’s valves and membranes. Your breast pump’s valves and membranes work together to create a seal around your nipple and facilitate suction; when they get old or break, that suction decreases.
When you notice cracks, tears or defects of any sort in these pieces, it’s time to replace them. As a note, you should be regularly replacing these parts of your pump even if they aren’t broken (valves every two or three months, membranes every two weeks to two months).
