The 17.5mm umbrella check valve is a precision silicone one-way valve specially designed for vacuum squeeze bottle packaging and liquid freshness preservation applications. Its optimized umbrella structure provides reliable sealing performance and smooth liquid dispensing while helping maintain vacuum conditions inside the bottle.
This silicone umbrella valve is widely used for high-freshness liquid products such as sushi soy sauce, edible oil, seasoning sauces, and other sensitive liquid condiments. During dispensing, the valve allows liquid to flow out smoothly while preventing outside air from entering the container, helping reduce oxidation and extend product shelf life.
The umbrella check valve provides stable one-way flow control together with excellent leak-proof sealing capability. Even when the bottle is stored upside down, the valve helps prevent liquid leakage, improving packaging reliability during storage, transportation, and daily use.
The umbrella sealing surface is designed with reinforced rib structures that help improve dimensional stability and deformation resistance. This reinforced structural design enhances sealing consistency and helps maintain stable valve performance during repeated squeezing and dispensing cycles.
Manufactured using high-precision heat press molding technology, the valve is processed with precision punching tools to ensure consistent outer dimensions, clean cutting edges, burr-free surfaces, and stable sealing quality. The precision manufacturing process helps improve product consistency and long-term reliability.
Made from premium food-grade silicone rubber, the valve offers excellent flexibility, elasticity, and environmental resistance. Hopewell supports custom silicone umbrella valve development with customized dimensions, hardness, colors, opening pressure, and structural designs according to different packaging and dispensing requirements.
