Dairy Plant Valves

Types of Valves Used in Dairy Plants

Dairy plants use hygienic stainless-steel valves to control milk, cream, yogurt, butter, whey, cleaning chemicals, steam, and CIP (Clean-In-Place) systems. These valves are specially designed for sanitary processing, easy cleaning, corrosion resistance, and contamination prevention.
