Was sollten Sie wirklich über Silikonventile wissen, bevor Sie sie für Ihre Anwendung auswählen?

When it comes to flow control and leak-proof dispensing, silicone valves play a critical role across industries—from food and beverage packaging to medical devices and personal care products. Many people initially think of silicone valves only as sealing gaskets. In reality, they are far more advanced. Modern silicone check valves not only provide airtight sealing but also dispense liquids and gases with precision, regulate flow under preset pressure, and prevent backflow.

At YJCPolymer, a leading silicone valve manufacturer and factory in China, we’ve specialized in designing and producing high quality silicone control valves for over a decade. Through continuous innovation and automation, we offer OEM service and custom solutions to meet the specific needs of global customers. In this blog, we’ll take you through the classifications, designs, benefits, and real-world applications of silicone valves—while also showing you why working with a professional supplier matters.

What Makes Silicone Valves Different?

A silicone valve, often called a silicone check valve, is an elastic one-way or two-way valve that uses the flexibility of silicone rubber to control dispensing. These valves can be manufactured using:

• Solid Silicone Rubber (via compression molding): Ideal for colorful, small-batch, and leak-proof dispensing applications.
• Liquid Silicone Rubber (LSR) (via injection molding): Perfect for precision parts requiring transparency, tight tolerances, and high repeatability.

Silicone’s unique material properties—excellent elasticity, high tensile strength, biocompatibility, and resistance to extreme temperatures—make it the preferred choice for industries where consistent flow control and long-term durability are essential.

Classification of Silicone Valves by Design

Depending on shape and function, silicone valves are engineered into various types. Each design is optimized for different applications:

1. Cross Slit Silicone Valves

These valves feature a cross or snowflake-shaped slit, making them ideal for squeeze dispensing systems in food and beverage products such as ketchup, mayonnaise, syrups, vinegar, soy sauce, and concentrates.

• Available in different outside diameters (9.8mm, 10.5mm, 16.5mm).
• Leak-proof tested with 24/7 inverted tests and dispensing angle verification (±15 degrees).
• Perfect balance between dispensing precision and no-drip performance.

At YJCPolymer, we’ve invested in automated production lines for cross slit valves, increasing daily output up to 200,000 pcs per line while reducing defective rates significantly. This ensures not only consistency but also scalability for mass production.

2. Silicone Duckbill Valves

Shaped like a duck’s beak, these one-way valves open under forward pressure and seal tightly when flow stops. They can also be combined with umbrella valves for two-way flow.

• Widely used in liquid dispensing and backflow prevention.
• Available in standard public molds (12.5mm O.D.) and fully customized per OEM drawings.
• Trusted in industries like healthcare, packaging, and consumer products.

As an experienced manufacturer in China, YJCPolymer develops custom duckbill valves to fit unique dispensing systems worldwide.

3. Silicone Umbrella Valves

Also known as mushroom valves, umbrella valves allow two-way functionality. They are frequently used in hydration bottles, respiratory devices, and flavor control systems. Their dome shape provides efficient sealing under low pressure while allowing smooth flow when needed.

4. Flapper Valves

These one-piece valves are commonly used in first-in-first-out (FIFO) squeeze bottles for condiments like ketchup and mayonnaise. In medical devices, silicone flapper valves serve as compact check valves for precise flow control.

5. Conical Silicone Valves

Specially designed for cosmetics and skincare packaging, conical valves feature asterix-style slit cuts for dispensing eye cream and other high-viscosity formulations with precision.

6. Dome Silicone Valves

These valves are widely used in liquid soap dispensers and dish brushes. With undercut designs, dome valves can be directly assembled without a separate plastic valve seat, reducing part counts and simplifying manufacturing.

7. Custom Silicone Valves

Every industry has unique needs. At YJCPolymer, we provide OEM service to design and manufacture custom silicone valves based on customer drawings, specifications, or performance requirements. From medical-grade valves to industrial sealing solutions, we tailor products to meet global standards.

Quality, Certifications, and Manufacturing Excellence

Producing silicone valves isn’t just about molding parts—it’s about ensuring reliability, safety, and regulatory compliance. That’s why our factory in China is fully certified with:

• ISO 9001 (Quality Management)
