Overview
Our Customized 9.8mm Medical-Grade One-Way Cross-Slit Silicone Dispenser Valves are engineered for mess-free, sterile dispensing in travel-size silicone bottles and personal care dispensers. Manufactured from medical-grade liquid silicone rubber (LSR) using precision LSR injection molding and micro-slit tooling, the 9.8mm cross-slit geometry delivers reliable one-way flow, fast reseal, and zero drip under variable pressures. Cleanroom molding, validated opening-pressure control, and sterilization-ready packaging make these valves ideal for medical, pharma-adjacent personal care, and high-hygiene travel applications.

Key Benefits
- Leak-proof performance: Cross-slit geometry ensures rapid reseal and eliminates dripping or backflow.
- Medical-grade safety: LSR meets biocompatibility requirements for skin-contact and cosmetic/medical applications.
- Precise flow control: Tunable opening pressure and slit dimensions for consistent dosing and consumer feel.
- Sterile-ready supply chain: Cleanroom molding, validated sterilization, and lot traceability simplify regulatory uptake.
Quality Assurance
All valves follow a medical-grade QA workflow: incoming LSR batches are certified and traceable; molds are validated with trial runs and capability studies; in-line dimensional checks use 3D optical projectors and CMM sampling; functional testing includes opening-pressure calibration, pressure-decay leak tests, and lifecycle actuation (fatigue) testing. Sterility and packaging integrity tests are performed per customer specification. Full documentation (material certificates, test reports, lot traceability) is provided for each shipment.
Type of Silicone Valves
- Standard 9.8mm Cross-Slit Valve — baseline opening pressure for consumer travel bottles.
- Low-Pressure Cross-Slit — tuned for thin liquids and low-force dispensing.
- Reinforced Collar Valve — with a molded collar for secure press-fit into bottle caps.
- Flanged Snap-In Valve — for rapid assembly into thermoplastic closures.
Factory Capabilities
Our production facility combines precision LSR injection molding with micro-tooling: dedicated micro-LSR presses, multi-axis CNC and mirror EDM for mold cavities, and slow-speed wire cutting for fine slit tooling. We operate ISO-certified cleanrooms for assembly, use automated leak and opening-pressure test rigs, and maintain inspection assets including ZEISS CMMs, 3D optical scanners, Shore durometers, and long-life fatigue testers. Sterile packaging lines and validated sterilization partners support medical and hygiene applications, while in-house rapid prototyping accelerates design verification.
