3-Way Normally Closed 3-Wire Magnet Latching Valve — Exhaust to Atmosphere This type of valve is often used in remote areas where continuous power may not be available or with battery-powered portable equipment where power capacity is limited. It is also valuable in equipment where coil heating, due to continuous application of power, is undesirable. Air, water and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require other seal materials. • Meets today’s demand for economy of space. • Uses power only during latching and un-latching. • Great for medical and chemical analyzers.
