Overview
The Custom Silicone Ketchup Valve is a purpose-built, food-safe check valve engineered specifically for condiment dispensing — designed to provide consistent flow, prevent dripping, and resist clogging from viscous sauces like ketchup and barbecue. Manufactured from premium food-grade silicone or LSR compounds using precision molding and automated LSR injection systems, these valves are tailored for squeeze bottles, pump dispensers, tabletop dispensers, and food-service equipment. Full OEM services include geometry optimization for target viscosity, custom shore hardness, integrated mounting features, color matching, and secondary assembly options to meet your brand and application requirements.

Benefits of Our Ketchup Valves
- Drip- and Mess-Reduction — tailored umbrella and seat geometry minimize after-drip for cleaner dispensing.
- Optimized for Viscous Fluids — flow channels and membrane stiffness tuned to ketchup-style viscosities to ensure consistent dosing.
- Anti-Clog Design — engineered passages and surface finishes reduce product build-up and help maintain consistent flow over time.
- Food-Safe & Odor-Free — FDA/LFGB-compliant compounds prevent taste or odor transfer and resist staining.
- Fast Elastic Recovery — low-hysteresis silicone returns rapidly for repeatable dispensing cycles.
- Easy to Clean & Sanitize — tolerant of common food-service cleaning agents and thermal sanitation cycles.
Quality Assurance
Our quality assurance for the Custom Silicone Ketchup Valve relies on certified systems and application-focused testing to guarantee food-safety and functional reliability. We operate under ISO 9001 processes and use FDA/LFGB-compliant LSR/VMQ compounds. Each production lot is monitored with closed-loop process controls (shot weight, temperature, pressure) and 100% visual inspection for flash, forming defects, and surface finish. Functional testing includes automated leak/back-pressure tests, flow-rate verification using standardized ketchup simulants, cycle-life endurance runs, compression-set measurement, and dimensional verification via CMM. For food-industry customers we supply migration/extractables reports, sensory (taste/odor) screening, and full lot traceability and material certifications on request.
