Silicone Valves for Precise and Leak-Proof Fluid Dispensing

Silicone valves, also known as elastomeric valves, are designed to provide accurate and consistent control of fluid and air flow under specific pressure or vacuum conditions. These precision-engineered components are typically made from high-quality silicone and rubber materials and are manufactured using advanced processes such as liquid silicone rubber (LSR) injection molding. Common types include one-way valves, cross slit valves, duckbill valves, and umbrella valves, each offering unique performance characteristics for various applications—from medical devices to dispensing systems. For durable, reliable, and custom rubber valves, Contact YEJIA to ensure quality, consistency, and engineering support.

Types of Silicone Valves

YEJIA offers a wide range of custom silicone valves, designed to ensure consistent, one-way flow control for liquids, gases, or air. From cross slit valves to duckbill valves, umbrella valves, flapper valves, and other rubber valve types, our solutions are engineered for reliability, hygiene, and durability across industries like food packaging, medical devices, automotive, and personal care.

Rubber Valve Types	Cross-Slit Valve	Duckbill Valve	Umbrella Valve	One-Way Valve	Flapper Valve
Introduction	Cross slit valves are designed for controlled dispensing in squeeze bottles, caps, and industrial systems. Their self-sealing, one-way slit design prevents leaks and ensures precise, drip-free flow, resealing automatically after each use.	Duckbill valves are one-way check valves that open under forward pressure and close tightly to block reverse flow. Their duckbill-shaped design ensures reliable sealing and efficient performance even under challenging conditions.	Umbrella valves are check valves that offer low opening pressure and effective sealing, ideal for venting and pressure relief applications. The umbrella-shaped diaphragm opens to allow forward flow and closes to prevent backflow.	One-way valves are molded elastomeric valves that enable unidirectional flow and prevent contamination or leakage. Their high-performance silicone material provides outstanding weather resistance, flexibility.	Flapper valves offer hygienic and efficient flow control for low-pressure systems. They operate by bending under forward pressure and sealing tightly against reverse flow. Common uses include fluid dispensing systems.
Feature	Self-sealing, variable flow rate under pressure	One-way flow, low cracking pressure, easy assembly	Excellent backflow prevention, compact design	Unidirectional flow control and prevent backflow	High flow efficiency, directional sealing
Applications	For food, cosmetics, and cleaning product packaging	Medical Devices, Industrial Fluid Control use	Respiratory devices, Consumer Electronic Products	Electronics, Baby Products	Personal Care, Cosmetic Packaging

Applications of Silicone Valves

Silicone valves have become an essential component in many industries due to their excellent properties, including flexibility, durability, and resistance to high temperatures. These valves have found their way into various applications, including food and beverage production, household cleaning agents manufacturing, personal care products dispensing control, medical devices such as catheters and feeding tubes.

▲ Food & Beverage: Squeeze bottles, sauce dispensers, condiment caps
▲ Medical & Healthcare: Ventilation masks, fluid control, drug delivery
▲ Cosmetics & Personal Care: Shampoo bottles, lotion pumps
▲ Automotive: Pressure relief systems, fluid reservoirs
▲ Consumer Products: Cleaning agents, household packaging

Food & Beverage	Consumer Products	Cosmetics& Personal Care	Medical Devices& Healthcare
In the food and beverage industry, silicone valves are used in the production of dairy products, ketchup, honey, mayonnaise, juices, sauces, and other beverages. They are also used in the packaging of food products to ensure that they remain fresh for longer periods.	In household cleaning agents manufacturing processes such as detergents and disinfectants production process silicone valves are used . They are also used in the packaging of these products to ensure that they are easy to use and that the contents remain fresh for longer periods.	In personal care products such as shampoos, conditioners, lotions silicone valves are used to control the dispensing of the product. The valves ensure that the right amount of product is dispensed making them cost-effective for manufacturers.	In medical devices such as catheters and feeding tubes silicone valves are used to control the flow of fluids. The valves are preferred in this industry due to their bio-compatibility which means that they do not harm the body.

Mold Design& Mold Making	Silicone Molding	Slit Cutting	Quality Inspection
The first step in manufacturing silicone valves is mold design and mold making. A professional engineering team with experience in silicone molding and advanced mold making equipment is crucial to ensure high precision and meet the highest standard of the industry. The mold is designed according to the required specifications of the valve, such as size, shape, and material. Once the mold is created, it is ready for silicone molding.	After the mold created, the silicone rubber is prepared for molding either to be injected into or to be put into the mold. During the curing process, the silicone rubber hardens and takes on the shape of the mold. The curing time can vary depending on the size and complexity of the valve, as well as the specific type of silicone being used. Once the curing process is complete, the valve is removed from the mold and inspected for quality.	After the valve is removed from the mold, it undergoes slit cutting. Slit cutting is a process where a thin blade is used to cut a slit in the valve. This slit allows the valve to open and close as needed to control the flow of liquids or gases. The slit cutting requires precision to ensure that the slit is cut at the right angle and depth. YEJIA has developed the automatic punching equipment, not only improve the daily capacity, but also redue the defective rate.	The key steps in manufacturing silicone valves is quality inspection. The valve is inspected for any defects or imperfections that may affect its performance. Quality inspection ensures that the valve meets the required specifications and standards of the industry. Only after passing quality inspection, the valve is ready for shipment, so we can guarantee the right use in various industries.
