Wholesale 13mm Silicone Umbrella Valve | Custom Silicone Diaphragm Check Valve Manufacturer – YEJIA

13mm silicone umbrella valve is a one-way check valve made from flexible silicone rubber, featuring an umbrella-shaped diaphragm with an outer diameter of approximately 13 mm. It allows fluid or air to flow in one direction while preventing backflow in the opposite direction.

The valve consists of a stem and a thin umbrella-shaped sealing membrane.

• When pressure is applied from the inlet side, the membrane lifts slightly, allowing fluid or air to pass through.

• When the pressure drops or reverses, the membrane returns to its sealing position, preventing backflow.

• The simple design provides reliable one-way flow control without springs or complex components.

Product Information

Advantages of 13mm Silicone Umbrella Valve

1. Reliable One-Way Sealing

The umbrella-shaped diaphragm creates a tight seal when pressure is removed or reversed, effectively preventing leakage and backflow.

2. Low Cracking Pressure

The flexible silicone membrane opens easily under low pressure, ensuring smooth fluid or air flow while minimizing resistance.

3. Wide Temperature Range

Silicone umbrella valves can operate reliably in both high- and low-temperature environments, typically from -40°C to 200°C depending on the material grade.

4. Long Service Life

The one-piece molded design contains no springs or moving mechanical parts, reducing wear and ensuring long-term performance.

5. Food-Grade and Medical-Grade Options

The valve can be manufactured from FDA-compliant or medical-grade silicone, making it suitable for food, beverage, healthcare, and infant-care products.

6. High Flow Efficiency

The 13 mm size offers a larger flow path compared with smaller umbrella valves, enabling faster dispensing and improved fluid transfer.

FAQ

1. What is a 13mm Silicone Umbrella Valve?

A 17.5mm Silicone Umbrella Valve is a type of one-way (check) valve made from flexible silicone rubber, designed with an “umbrella-shaped” diaphragm and a nominal diameter of 17.5 mm. The valve consists of a thin, dome-shaped sealing head attached to a stem. It’s typically installed into a seat or orifice. When pressure is applied from one side, the “umbrella” lifts to allow flow; when pressure stops or reverses, it closes tightly to prevent backflow.

2. What materials are used for the 13mm Silicone Umbrella Valve?

The valve is typically made from liquid silicone rubber (LSR), available in: Food-grade silicone; Medical-grade silicone; Industrial-grade silicone. 

Material selection depends on the application requirements.

3. Is the valve suitable for food or medical use?

Yes, if produced with certified materials. Food-grade and medical-grade silicone can comply with relevant standards such as FDA or ISO requirements, making the valve safe for sensitive applications.

4. Can YEJIA customize the size and slit design of silicone valves?
Yes, we offer full customization, including valve size, slit type, hardness, and coating options, to meet your specific product requirements and packaging compatibility.

5. Are 13mm Silicone Umbrella Valve food grade?

Yes. High-quality silicone valves are typically made from food-grade silicone, which complies with standards such as FDA, LFGB, or other international food safety regulations.

6. What are the advantages of 13mm Silicone Umbrella Valve?

·  Excellent sealing performance

·  Fast response to pressure changes

·  Wide temperature resistance (-40°C to 200°C)

·  Chemical and aging resistance

·  Long service life

·  Maintenance-free operation

7. How does YEJIA ensure the quality and consistency of 13mm Silicone Umbrella Valve?
YEJIA implements strict quality control at every production stage, including material inspection, precision molding, coating application, and final performance testing to ensure consistent flow, anti-drip functionality, and durability.

8. What is the MOQ for custom silicone valves?

The minimum order quantity (MOQ) for custom silicone valves depends on the valve size, mold design, and production process. YEJIA provides prototype testing samples before mass production to ensure proper performance and compatibility with your packaging system.
