This special little valve has been designed to provide a steady flow of
liquid and therefore a smooth drinking action, while preventing liquid
from flowing back into the spout when your baby is not drinking from
the cup.
The special band on the VitalValve™ allows liquid to flow through the valve when the child is drinking.
Ensure that the band is kept in place over the valve, especially after cleaning.
The air-release slit allows the flow of liquid through the valve.
To make sure that the VitalValve™ functions correctly, insert it into the spout and press firmly into position.
To remove the VitalValve™ grip the fin firmly and pull gently.
The VitalValve™ fits all Watties Baby Basics Cups and tumblers and is
removable giving you the option to use the valve or not.
