Overview
Our Custom Mini / Micro Medical-Grade One-Way Duckbill Silicone Check Valves are engineered for precise, leak-proof one-way flow control in critical medical applications — including IV sets, infusion pumps, respiratory devices, drug delivery systems, and surgical disposables. Manufactured from medical-grade liquid silicone rubber (LSR) and produced via micro-precision LSR injection molding, these duckbill valves deliver ultra-consistent opening pressures, excellent chemical compatibility, and reliable sealing over millions of actuation cycles. Cleanroom molding, sterile packaging options, and full regulatory documentation make these valves ready for integration into regulated medical assemblies.

Key Benefits
- Medical-grade safety: USP Class VI / ISO 10993 validated LSR ensures biocompatibility for patient-contact applications.
- Precise one-way control: Duckbill geometry tuned for repeatable opening pressure and fast reseal to prevent backflow and contamination.
- Miniaturized consistency: Micro-injection tooling and tight ±0.01 mm tolerances deliver uniform performance across large volumes.
- Sterile-ready & traceable: Cleanroom molding, lot traceability, and validated sterilization options simplify regulatory submissions and GMP integration.
Quality Assurance
We apply a medical-grade QA protocol covering raw material verification, in-process control, and final release testing: incoming LSR batches are spectrally analyzed and certified to USP/ISO standards; molds are validated with trial runs and CPK studies; parts undergo dimensional inspection (CMM / 3D optical), opening-pressure and leak testing (pressure decay/bubble test), Shore A hardness and tensile tests, and actuation life-cycle testing to simulate real use. Sterility validation and packaging integrity tests are carried out per customer spec. Full documentation (material certificates, IQ/OQ/PQ support, batch traceability) is provided.
Type of Silicone Valves (typical options)
- Mini Duckbill Check Valve — ultra-low opening pressure for micro-flow devices
- Micro Duckbill with Reinforced Collar — for secure press-fit into caps and assemblies
- Flanged Duckbill Valve — for snap-in integration with tubing or housing
- Multi-Port Mini Valve — multi-channel configurations for manifolded dosing systems
Factory Capabilities
Our factory combines micro-precision LSR injection molding with dedicated medical tooling: five high-precision micro-LSR molding presses, multi-axis CNC and micro-EDM for mold cavities, precision slow-speed wire cutting, and cleanroom assembly lines (ISO Class 7). QC tools include ZEISS CMMs, high-resolution 3D optical projectors, automated pressure/leak test rigs, Shore durometers, and fatigue cycling stations. We support rapid prototyping, DFM consultation, pilot runs, and scalable mass production with sterile packaging and regulatory support to meet medical industry timelines.
