have flexible diaphragms, or bellows, to isolate operating parts from fluids. Removing metal-to-fluid contact eliminates corrosion, contamination, and clogging in wetted valves. The valves feature all-Teflon construction, are available in twoway normally closed and normally open and three-way configurations, use Viton, EPDM, and Teflon seals, and standard voltages of 24 Vdc and 115 Vac/60 Hz, and pressures range from vacuum to 100 psi and flow rates up to Cv 3.5.
