STAINLESS STEEL Sanitary Wafer Dosing DN25 butterfly valve
The STAINLESS STEEL Sanitary butterfly valve is a compact, food-grade valve designed for precise dosing and flow control in hygienic pipelines, featuring stainless steel construction and wafer-type installation.
Working Principles
The stainless steel sanitary wafer dosing DN25 butterfly valve operates by precisely controlling fluid flow through the rotation of a centrally mounted butterfly disc. When the actuator or manual handle is adjusted, the valve shaft rotates, moving the disc to a specific angle that determines the flow rate. Unlike simple on–off valves, the dosing design allows fine positioning of the disc, enabling accurate and repeatable flow regulation for small volumes. The sanitary stainless steel body features smooth internal surfaces to minimize residue buildup and support effective cleaning. The wafer-type structure allows the valve to be installed between pipe flanges with minimal space requirements. This working principle makes the valve suitable for hygienic dosing applications in food, beverage, pharmaceutical, and biotechnology processing systems where precision, cleanliness, and reliability are essential.
