Silicone Breast Pump Valve, also called as Breast Pump Duckbill Valve, Silicone Duckbill Valve, Duckbill Check Valve, Liquid Silicone Duckbill Valve, which is one kinds ofone way and non returen valve with duck shaped bills & lips in aim to allow air or fluid liquid milk forward flow and also prevent backflow.
Breast Pump Duckbill Valve is mainly made from FDA food grade liquid silicone rubber by LSR Injection Molding machines. 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.
Duckbill Valve's main advantage is 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.
LSR Silicone Duckbill valves are widely used as fluid control & hydraulic system in automobiles, small machine, electrical appliance and medical areas. Different working environment require different material properties. For babycare used device, we usually suggest to choose liquid silicone rubber, because the material safety is higher than solid food grade silicone. Liquid Silicone Rubber is a inorganic nature, which is clean, plasticizer-free, tasteless, odorless and can proof water, resist oxidation and some chemical materials like acids and alkali.LR 3038 40 K1 10993-5 E.PDF
Breast Pump Duckbill Valve of Liquid Silicone Rubber & LSR is resistant to bacteria growth and can be sterilized by steam antoclaving, ethylene oxide, gamam, e-beam etc.
