The 16.5mm no drip silicone valve is engineered for controlled dispensing applications that demand both high flow performance and reliable sealing. Its flat membrane structure sets it apart from traditional domed valves by significantly reducing opening force while still maintaining strong closure integrity after dispensing.
Featuring a precisely engineered 11×11mm cross slit, the valve delivers a smooth and consistent flow for medium-to-high viscosity products such as sour cream, sauces, and thick condiments. The optimized slit geometry minimizes flow resistance and ensures stable dispensing, even for formulations containing small particles.
Unlike conventional designs, the flat-profile structure enables quicker response and easier actuation, improving the overall user experience in squeeze packaging. This makes it especially suitable for consumer-friendly applications where consistent and effortless dispensing is critical.
Manufactured from high-quality 50 Shore A liquid silicone rubber (LSR), the valve provides excellent elasticity, tear resistance, and rebound performance. This material balance ensures long-term durability, stable sealing behavior, and resistance to deformation under repeated use cycles.
The valve is produced using advanced LSR injection molding combined with automated precision slitting, ensuring tight dimensional tolerances and highly consistent slit quality across mass production. For optimal functionality, it must be assembled with a rigid plastic housing to achieve proper compression sealing and prevent leakage under pressure or inverted storage conditions.
Designed for leak-proof performance, the valve maintains a secure seal even when the container is stored upside down. Made from FDA-compliant food-grade silicone, it is safe for direct food contact and offers excellent resistance to oils, acids, and temperature variations, making it suitable for a wide range of food and liquid dispensing applications.

The 16.5mm cross slit no drip valve is widely used in packaging systems that require controlled dispensing and leak prevention:
Sour cream and dairy product pouches
Sauce and condiment squeeze bottles
Sports water bottles and hydration systems
Personal care products (creams, gels, lotions)
Cleaning liquids with medium to high viscosity
Refillable soft packaging solutions
Its high flow capacity and low opening force make it especially suitable for consumer-friendly squeeze applications.
This valve is ideal for medium to high viscosity products such as sour cream, sauces, gels, and thick liquids that require smooth dispensing without clogging.
No. The valve is specifically designed for inverted storage and provides reliable no-drip sealing when not in use.
The valve relies on structural compression from a hard plastic housing to maintain sealing integrity. Without proper support, leakage or poor performance may occur.
The flat design reduces opening pressure, making dispensing easier while still maintaining effective sealing after release.
Yes. The slit dimensions, opening force, and flow rate can be customized based on your product requirements and packaging design.
Yes. The valve is made from FDA-compliant food-grade liquid silicone rubber, suitable for direct contact with food products.
