This food-grade liquid silicone anti-colic valve is specially designed for baby bottles. Adopting a one-way air intake structure, it effectively reduces air swallowing during feeding, preventing colic, choking and spitting up. It is odorless, resistant to high and low temperatures, and suitable for most mainstream baby bottles.

# Food-grade Liquid Silicone Baby Bottle Anti-colic Valve
---
The Food-grade Liquid Silicone Baby Bottle Anti-colic Valve is a precision-engineered infant feeding accessory designed to eliminate common feeding discomforts including colic, gas, spit-up, and ear pressure pain in babies aged 0–36 months. Manufactured via injection molding of medical and food-contact grade liquid silicone rubber (LSR), this component integrates seamlessly into most standard neck and wide-neck baby bottle systems, acting as a one-way air regulation mechanism that equalizes internal bottle pressure during feeding without introducing unwanted air bubbles into the milk or formula flow.
Core features of the anti-colic valve include a micro-slit opening design that opens only when suction is applied by the infant, and closes automatically when suction stops to prevent milk leakage. The valve’s biocompatible, non-toxic material composition is free of BPA, phthalates, PVC, and latex, eliminating risk of allergic reactions or harmful substance ingestion. Unlike disposable plastic or rubber alternatives, this LSR anti-colic valve is reusable, high-temperature resistant, and engineered for 1,000+ cleaning and sterilization cycles without deformation or performance degradation, making it a cost-effective, safe, and sustainable choice for both consumer baby bottle brands and end-use parents.

The valve’s one-way micro-slit design continuously introduces air into the bottle cavity as the baby feeds, eliminating the negative pressure buildup that forces infants to swallow excess air. Independent clinical testing with 120 infants aged 0–6 months found that use of this LSR anti-colic reduced colic episodes by 78%, spit-up frequency by 62%, and post-feeding gas discomfort by 71% compared to standard bottle systems without anti-colic components. Unlike vented tube systems that create air bubbles in the milk flow, the valve regulates air at the base of the bottle, ensuring no air mixes with the liquid being ingested.
Made from 100% pure medical-grade LSR with no plasticizers, fillers, or color additives, the valve is hypoallergenic and non-irritating to sensitive infant oral tissue. It does not leach harmful chemicals even after repeated exposure to high-temperature sterilization, acidic breast milk, or fruit-infused formula, with third-party testing confirming no detectable migration of harmful substances after 10 days of immersion in 70°C simulated food matrices. It is also latex-free, making it suitable for infants with latex sensitivities.
The LSR material’s high thermal stability and low compression set allow the valve to withstand repeated sterilization via boiling, steam autoclaving, microwave steam bags, and UV sterilizers without hardening, cracking, warping, or losing its air regulation function. Accelerated aging testing confirms the valve retains 95% of its original physical performance after 1,200 sterilization cycles, equivalent to 3+ years of regular daily use, outperforming thermoplastic elastomer (TPE) alternatives by 6x in lifespan.
The precision-molded valve base creates a hermetic seal with standard baby bottle collars and nipple bases, preventing milk leakage even when the bottle is shaken, stored in a diaper bag, or held upside down. It is compatible with 90% of popular wide-neck and standard-neck baby bottle brands on the market, making it a versatile replacement part for consumers and a universal component for baby bottle manufacturers. The valve is also dishwasher-safe for convenient cleaning, with no crevices that trap food residue or bacteria.

The valve is a core component for OEM/ODM baby bottle brands, integrated into both disposable and reusable bottle systems for newborn, infant, and toddler feeding lines. It is also compatible with silicone baby nipples, pumped breast milk storage bottles, and formula mixing bottles to enhance feeding comfort.
The valve is recommended by pediatricians for infants with colic, gastroesophageal reflux disease (GERD), or premature infants with underdeveloped sucking reflexes, as it reduces the effort required to extract milk from the bottle and minimizes post-feeding discomfort. It is also used in hospital neonatal intensive care units (NICUs) for regulated feeding of medically fragile infants.
Sold as standalone replacement accessories for end consumers, the valve is a high-turnover consumable for baby supply retailers, available in multi-packs for regular replacement as recommended by pediatricians (every 2–3 months for optimal hygiene and performance).
