 Application: Cold deionized water from scale-operated batching tanks is blended with hot deionized water and hot oils in the manufacture of hair cosmetics.
Where In Process?: The flow of hot deionized water is maintained at a constant rate until emulsification of the product is complete.
Why Flow Rate is Critical?: The controlled addition of hot deionized water is necessary to establish emulsification of the product without excess air, which would cause foaming and in some cases a slight exothermic reaction.
What Alternatives Were Considered: Air loaded diaphragm control valves or ball valves.
Main Reasons for Choosing Kates: Convenience is being able to set the needed flow rate and get good repeatability without adjustment or supervision.
