      What is Silicone Valves?

      A silicone valve is a one-way valve specifically designed for fluid control, commonly used in liquid dispensing systems such as bottle caps, packaging bags, and more. It features a special cutting design that ensures no leakage when no external force is applied, and the liquid is only released when squeezed or pressed. Silicone valves are commonly found in packaging for food, daily chemicals, and pharmaceutical products, especially for those requiring precise flow control.

      These valves are typically made from LFGB and FDA-approved food-grade silicone materials, offering excellent high-temperature resistance, corrosion resistance, and superior sealing performance. Manufactured through advanced LSR injection molding technology, silicone valves are produced in a clean, dust-free environment, ensuring high quality and hygiene standards.

      Silicone valves effectively extend the shelf life of products while providing efficient fluid management solutions for various packaging needs. They are an indispensable component in modern fluid dispensing systems.
