OEM Leak Proof Ketchup Dispensing Silicone Valves Suppliers

Product Description:

Our OEM leak-proof silicone valves ensure precise, drip-free dispensing for ketchup and condiments. Engineered with a self-sealing diaphragm design from food-grade LSR, they provide reliable one-way flow control, easy cleaning, and superior hygiene. We offer full customization for integration into any packaging system.

Basic Information:

Quality Assurance:

Quality assurance for our dispensing valves centers on guaranteed leak-proof performance and food-contact safety. We begin with certified platinum-cure LSR that is 100% BPA-free and compliant with FDA and LFGB standards. The precision LSR injection molding process is calibrated to produce valves with consistent wall thickness and flawless sealing lips. Every production batch undergoes rigorous functional testing, including positive/negative pressure leak tests to validate the self-sealing action, dimensional checks of critical sealing surfaces, and cycle fatigue testing simulating thousands of compressions. We also perform cleanroom visual inspections and material certification audits to ensure every valve meets strict hygiene and performance standards for food dispensing applications.

Why Choose Us?

• Specialization in Functional Fluid Components: Our expertise is in designing and manufacturing precision silicone valves and diaphragms that solve specific flow control and sealing challenges in food and liquid packaging.

• Co-Engineering for Optimal Dispensing Performance: We collaborate closely with your team to engineer valve geometry (duckbill, umbrella, etc.) that delivers the desired flow rate, sealing force, and user experience for your specific product viscosity.

• Integrated, High-Precision LSR Molding: Our automated LSR injection molding lines and cleanroom handling ensure the production of micro-tolerance, flash-free valves with the consistency required for reliable automated assembly and end-use performance.

• Validation Through Real-World Simulation Testing: Our quality process includes application-specific tests such as viscosity-based flow rate checks, repeated compression cycling, and compatibility testing with various condiments to ensure long-term reliability.

Factory Show:

Our manufacturing facility is equipped with advanced, automated LSR (Liquid Silicone Rubber) injection molding systems specifically configured for high-volume production of micro-precision components like dispensing valves. In-house CNC and EDM departments guarantee the mold accuracy needed for complex valve geometries with critical sealing edges. For quality validation, we employ specialized equipment including custom-built leak testers that simulate real bottle pressure, high-magnification optical inspection systems for seal lip integrity, and precision durometers. A controlled cleanroom environment is utilized for the delicate demolding, curing, and packaging processes, ensuring the valves are protected from contamination and are ready for sterile food-contact applications.
