Series BSDA/BSDAM Miniature Air-Operated Diaphragm Valves

The miniature air-operated diaphragm valve that performs like a heavyweight. Designed for pressure and drain applications with highly corrosive or ultra-pure liquid systems when space is critical. The valve is ideal for a broad range of industrial applications, from electronic to chemical plants, commercial laundries, car wash operations, etc. For applications with ultra-pure water and concentrated etchants, such as in the semi-conductor industry, it provides the ultimate in non-leaching, contamination-free sealing. The standard valves use air pressure to open with spring return to close (0-100 psi). There is no minimum inlet pressure required. Additional sizes and materials available, call for quote.
