Overview
Our Customized Food-Grade LSR Flow-Control Cross Slit Ketchup Valves are engineered for reliable, mess-free dispensing in flip-top cap applications. Manufactured from 100% food-grade liquid silicone rubber (LSR) and finished with micro-precision cross-slit cutting, these valves provide controlled one-way flow, rapid reseal, and excellent anti-drip performance for high-viscosity condiments. Designed for OEM integration into retail squeeze bottles and flip-top closures, the valves are fully customizable in diameter, slit geometry, hardness, and color to match dispensing response and brand requirements.

Key Benefits
- Precise Flow Control: Cross-slit geometry and tailored shore hardness deliver repeatable portioning and smooth dispensing of viscous sauces.
- Drip-Proof Performance: One-way reseal and tight slit closure prevent leaks and stringing when bottles are inverted or stored.
- Food-Safe & Odor-Resistant: LFGB/FDA-grade LSR resists staining, flavor transfer, and food acids—ideal for condiment contact.
- Durable & Long-lived: Engineered for repeated actuation with stable elasticity across thermal cycles and extended shelf life.
- OEM Flexibility: Custom diameters, slit profiles, color matching, and private-label options to fit flip-top cap designs and brand packaging.
- Easy Cleaning & Assembly: Smooth non-porous surfaces simplify sanitation and automated assembly into cap inserts.
Quality Assurance
We manufacture valves under an ISO 9001 quality system with full material traceability. Incoming LSR batches are validated for LFGB/FDA compliance, then parts undergo dimensional verification (3D optical projectors and CMM), slit geometry inspection, and flow/leak testing on purpose-built rigs using ketchup-like fluids. Every production lot is subject to cycle life testing, durometer checks, and accelerated thermal/chemical exposure to verify reseal reliability and hygienic performance. Detailed inspection reports and batch certificates are provided with shipments.
Factory Capabilities
Our production facility is equipped for high-precision LSR tooling and molding: multi-axis CNC, mirror EDM, precision wire-cutting for micro slit tooling, 15 rubber compression presses and multiple LSR injection molding machines for volume runs. We operate automated micro-slit cutting stations, optical inspection lines, and dedicated flow/leak test benches. Quality equipment includes 3D projectors, sealing testers, durometers, and elasticity analyzers. Accredited to ISO 9001 (and able to support further customer audits), our end-to-end capability covers DFM, rapid prototyping, pilot runs, automated assembly, and custom packaging to support global condiment and food-service customers.
