Overview
Our Customized Food-Grade Silicone Rubber Drain Dispensing Cross Valves for Medical Usage are precision-engineered one-way valves designed for controlled, hygienic fluid transfer in medical devices, diagnostic kits, and clinical dispensing systems. Molded from platinum-cured medical-grade LSR or medical silicone, each cross-slit valve delivers reliable self-sealing, low opening pressure, and repeatable flow performance across repeated cycles. Designed for sterilization compatibility and biocompatibility, these valves support OEM customization of slit geometry, hardness, diameter, and packaging (sterile or non-sterile) to meet demanding healthcare requirements from prototype to high-volume production.

Key Benefits
- Medical-grade safety: Platinum-cured LSR options with ISO 10993 / USP Class VI biocompatibility available.
- Leak-proof, reliable sealing: Cross-slit geometry provides instant reseal and precise one-way flow.
- Sterilization ready: Designed to withstand standard medical sterilization methods without loss of performance.
- Fully customizable: Slit pattern, diameters, hardness, color (for coding), and sterile packaging per OEM spec.
Quality Assurance
All valves are produced under a documented quality system with full material traceability. Raw materials are verified against FDA/ISO 10993 declarations; in-process controls include dimensional checks (3D optical projectors), slit geometry inspection, and automated leak/flow testing. Finished lots undergo batch sampling for flow rate calibration, compression-set, tensile strength, and sterilization validation. For medical programs we supply full inspection reports, biocompatibility certificates, and serialization/traceability documentation in accordance with ISO 13485.
