Series 20 Model 22 Magnetic Latching

2-Way Normally Closed Valve
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 and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.
• Valve is magnetic latching.
• Meets today's demand for economy of space.
• Uses power only during latching and un-latching.
• Great for medical and chemical analyzers.
