Product Description
Silicone Rubber Cross Slit Valves- Leak-proof Dispensing Solutions
Cross slit valves are precision-molded silicone rubber valves featuring a cross-shaped slit on the sealing surface. These valves automatically open under pressure to allow controlled fluid dispensing and instantly reseal when pressure is released, preventing leaks or contamination. They can be made from food-grade silicone, medical-grade silicone, fluorosilicone, NBR, or other high-elasticity and weather-resistant rubber materials.
Applications of Cross Slit Valves
Cross slit valves are widely used in various consumer and industrial sectors where hygienic, precise, and drip-free dispensing is critical.
Main industries include:
◆ Food and beverage packaging (squeeze bottles, sauces)
◆ Cosmetics and skincare (lotions, gels, shampoos)
◆ Household cleaning (spray and dispenser caps)
◆ Personal care products (hand sanitizers, creams)

FAQ – Frequently Asked Questions
| Q1: What slit type should I choose for different liquid types? A: For thin liquids, smaller and tighter slits (like cross or Y-slit) work best. For thicker substances, larger or multi-slitted designs like snowflake or asterisk slits are recommended. |
| Q2: Can I request a custom cross slit valve with my own size or design? A: Yes, YEJIA specializes in custom silicone valve development and can produce tooling based on your requirements. |
| Q3: Are your valves safe for food contact? A: Absolutely. We use certified food-grade liquid silicone rubber that meets FDA and LFGB standards. |
| Q4: How do you ensure quality consistency? A: We use high precision LSR injection molding, automatic punching processes, and 100% AOI full inspection to maintain high consistency in every batch. |
| Q5: What's the lead time for mass production? A: For standard sizes, lead time is typically 7–10 days. Custom projects may vary depending on tooling and validation. |
