AVM's weir type diaphragm valves feature a raised weir design that provides precise flow control and tight shut-off, ideal for corrosive, viscous, or particulate-laden media. The diaphragm, made from PTFE, EPDM, or NBR, isolates the stem from the flow path, eliminating packing leaks. Constructed from 316L stainless steel or ductile iron, these valves meet DIN, ISO, and 3A standards, with electropolished surfaces for sanitary applications. Engineered using Japanese Mazak CNC technology, they offer reliable performance in pharmaceutical, water treatment, and chemical processes.
