Dairy Valves
What are Dairy Valves?
Dairy Valves are precision-engineered flow control devices used in sanitary process systems to regulate, isolate, or divert fluid flow in a hygienic manner. These valves are essential for maintaining product purity and process efficiency in industries such as dairy, food, beverage, and pharmaceuticals.
Asiad Steel Industries is a leading manufacturer and supplier of high-quality dairy valves, available in stainless steel 304/316L with polished interiors and end connections that match SMS, DIN, and ISO standards.
