Description:
Our precision-engineered silicone cross slit valves are manufactured through advanced compression molding using 100% FDA-compliant, platinum-cured silicone rubber to deliver reliable leak-proof performance for viscous fluids, creams, and pastes. Designed with a self-sealing cross-slit diaphragm, these valves ensure precise dispensing control, prevent backflow, and maintain airtight integrity under pressure fluctuations. Rated for temperatures from -60°F to 400°F and compatible with aggressive chemicals (acids, alcohols, and oils), they exceed FDA, LFGB, and USP Class VI standards. As your dedicated manufacturing partner, we provide end-to-end OEM solutions—including custom valve diameters (5–50mm), slit configurations, durometer hardness (Shore A 30-70), and sterilization compatibility—backed by high-volume compression molding capabilities. Ideal for pharmaceutical, cosmetic, and food dispensing applications demanding hygiene and reliability.

Quality Assurance:
Our quality process includes raw material certification (FTIR spectroscopy for purity), dimensional validation via optical comparators (±0.05mm tolerance), and functional testing (pressure hold tests per ASTM D4991, slit actuation force checks). We utilize Shore A durometers for hardness control, burst pressure testers (up to 50 psi), and cleanroom production (ISO Class 8) to ensure particulate-free outputs. All valves undergo 100% inline inspection and comply with ISO 9001 and cGMP standards.
