2-Way Reverse Polarity Magnetic Latching 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, as it only uses power during latching and un-latching. It is also valuable in equipment where coil heating, due to the continuous application of power, is undesirable. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.

• Kel-F pin sealing element.
• Orifice guides the sealing pin for perfect alignment.
• Simple construction — only two moving parts.
• Through the use of a permanent magnet, the latching valves are bi-stable in either shifted state. This allows the valve to stay in either state indefinitely without drawing power. To shift the valve from one state to another, a short 50 millisecond DC voltage is applied to the coil. To shift the valve back, a reverse polarity pulse is applied to the coil. This feature makes this valve suitable for use in remote areas where continuous power may be limited. It is also valuable in equipment where coil heating, due to a continuous application of power, is undesirable such as in medical and chemical analyzers.
