Plastomatic air operated diaphragm valves
Designed for pressure and drain applications processing ultra-pure water and corrosive chemicals.
Compact valves for corrosive and ultra-pure liquids in PVC, PTFE, Kynar® & Polypropylene
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 are air pressure to open with spring return to close (0-100 PSI). There is no minimum inlet pressure required. Other options are available. Not designed for Chlorine.
