Silicone Valves for Leak-Proof Dispensing Solutions

A silicone valve is a one-way, self-sealing component made from medical or food-grade silicone rubber material. Designed to control fluid or air flow, these valves are highly flexible, durable, and capable of withstanding extreme temperatures and harsh environments. Compared to conventional rubber or plastic valves, silicone valves offer superior chemical resistance, biocompatibility, and elasticity. 

For over a decade, Hopewell has specialized in manufacturing LSR injection molded silicone products and has established itself as a leading producer of silicone valves. Our expertise allows us to offer a diverse range of products tailored to meet specific flow control dispensing needs.

Features of Hopewell's Silicone Cross Slit Valves

Hopewell's silicone cross slit valves are made of FDA and LFGB silicone materials, ensuring great elasticity and flexibility. The unique slit cuts guarantee zero clearance and 100% qualified dispensing function. The non-stick slit and precision punching tool further enhance the valve's performance.

• 1. Silicone valves are made of FDA&LFGB silicone materials, with great elasticity and flexibility.

• 2. Slit cuts can guarantee zero clearance, and the function of dispensing is 100% qualified.

• 3. Unique technique makes the slit to be non-stick, won't affect the funtion of silicone valves.

• 4. Made by imported precision punching tool, the dispensing angle can be controlled with±15 degrees.

• 5. One squeeze, one dispensing, no leakage after 24*7 days inverted leak proof test.

Applications of Silicone Valves

Silicone valves are designed to prevent leakage and spills, ensuring precise dispensing and maintaining the freshness of liquids. They are ideal for dispensing water, syrup, spreads, and soy sauce while preventing mess and facilitating controlled release. Additionally, they are suitable for active use in sports and help preserve the quality and flavor. We can also collaborates with customers to develop more applications for silicone valves. Our molded silicone valves are ideal for:

•  - Food & Beverage: Squeeze bottles, condiment dispensers, drink lids

•  - Personal Care: Shampoo, lotion, sanitizer caps

•  - Medical Devices: Drug delivery systems, respiratory equipment, fluid control valves

• - Industrial Use: Chemical dispensers, air control systems, venting seals
