Sanitary Three-Way Diaphragm Valve
The Three-Way Diaphragm Valve incorporates a T-shaped or Y-shaped body with three ports and two diaphragm seats, enabling flow diversion, mixing, or distribution between two process lines using a single valve body. It eliminates the need for two separate two-way valves and associated fittings, reducing installation space, dead volume, and potential contamination points. The design maintains full hygienic integrity across all three ports.
