PRODUCTION PROCESS OF 13MM CROSS-
SLIT Valves
13mm cross-slit silicone valves are produced by liquid 
13mm cross-slit injection molding, further processed by automatic slit 
cutting and trimming. It undergoes precision silicone 
silicone valves molding to ensure uniform size and wall thickness.
The cross-slit valve also undergoes automatic slit 
Automatic slit cutting and burr punching with stable pressure to 
cutting and burr achieve leak-proof, flow control, and precise liquid 
dispensing.

APPLICATIONS of 13mm Cross-
Slit Valves
1 The 13mm cross-slit leak-proof silicone valve is specially designed for all types of 
reusable water bottles. This no drip cross-slit valve is commonly used in soft 
water bags for outdoor adventures, energetic sports water bottles, and safe 
children's water bottles.
2 Its unique wall thickness process ensures excellent leak-proof performance, 
guaranteeing the safe storage of every drop of precious water. The combination 
of top thickness and precision cross incision prevents leaks even under vigorous
