Silicone Valve
Custom silicone micro duckbill valve
Medical grade silicone raw material
MOQ: 50,000 pcs/lot
DESCRIPTION
Specification
Hopewell specializes in custom micro duckbill valves manufactured from solid silicone rubber using precision compression molding. Designed for medical fluid control applications, these one way micro duckbill valves allow fluid or air to pass in the intended direction while helping prevent backflow and leakage.
Featuring a flexible duckbill structure, the valve opens under the specified forward pressure and closes when the pressure decreases, providing reliable one-way flow control in compact medical devices.
With customized dimensions, material hardness, slit shape, and opening pressure, Hopewell provides micro silicone duckbill valve solutions tailored to different medical device designs and fluid handling requirements.

Product Information
A micro duckbill valve is a compact one-way valve featuring a flexible, beak-shaped outlet. Its slit remains closed under normal conditions and opens when sufficient forward pressure is applied, allowing fluid to pass through.
When the forward pressure decreases, the elastic silicone structure returns toward its original shape, closing the slit and helping prevent reverse flow.
Manufactured from solid silicone rubber, micro duckbill valves offer flexibility, elastic recovery, and a compact structure suitable for medical devices with limited installation space.
Compared with conventional rigid valve components, a silicone micro duckbill valve can provide a simple, integrated solution for directional fluid control without requiring a separate plastic holder.
Hopewell offers customized micro duckbill valves to meet different dimensional, sealing, and fluid control requirements in medical applications.

The duckbill slit opens under forward pressure and closes as the pressure decreases. This design helps control fluid direction and reduce unwanted backflow.
Solid silicone rubber provides flexibility and elastic recovery, allowing the valve lips to open and close in response to pressure changes. Material selection can be tailored to the intended application and required performance.
The micro-sized structure is suitable for applications where installation space is limited. Outer diameter, overall dimensions, and slit geometry can be customized to fit the device design.
The flexible valve lips come together when the opening pressure is removed, helping reduce leakage and reverse fluid movement. Actual sealing performance depends on valve geometry, material hardness, operating pressure, and fluid properties.
Opening pressure can be influenced by the slit configuration, valve dimensions, material hardness, and lip geometry. Hopewell can work with customers to develop a design that meets their specified flow and pressure requirements.
Compression molding is used to form the solid silicone rubber into the required valve geometry. Mold design and process control help support dimensional consistency and repeatable product performance.
Hopewell supports customized valve dimensions, silicone hardness, slit configurations, and colors to meet different medical device requirements. Material suitability and biocompatibility documentation should be confirmed according to the intended application and selected silicone compound.
