Product Description
Custom Food Grade& Medical Grade Silicone One Way Valves Supplier
Silicone one-way valves, also known as check valves, is an elastomeric component that allows the passage of fluids or gases in one direction while preventing backflow. These valves are typically made from food-grade or medical-grade silicone and designed with precise geometries to ensure reliable performance and hygienic sealing. They are widely used in dispensing systems, breathing devices, IV systems, and other flow control applications. Customizable in size, material, and opening pressure.
Key Features & Benefits

Types of Silicone One Way Valves YEJIA Offers
YEJIA offers several types of silicone one-way valves to meet your application needs:
◎ Duckbill Valves– Thin, flexible lips that open under pressure and close when the pressure is removed.
◎ Umbrella Valves – Dome-shaped valve with a central stem that seals and opens with pressure.
◎ Flapper Valves – Flat disc design that acts as a swinging door for fluid/gas flow.
◎ Custom One-Way Breathing Valves – Specially developed for masks, wearable devices, and airflow regulation.
All types can be customized in Shore hardness, dimensions, and opening pressure.
Typical Applications
Silicone one-way valves are ideal for:
◆ Medical devices (IV systems, catheters, masks)
◆ Food and beverage packaging (dispensing caps, squeeze bottles)
◆ Personal care products (shampoo, lotion pumps)
◆ Venting systems for electronics or batteries
◆ Airflow control in smart wearables
