Straight Magnetically Latching Valve uses a permanent magnet within the solenoid. To shift the valve from one state to another, a short 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. Straight Magnetically Latching Valve is also valuable in equipment where coil heating, due to a continuous application of power, is undesirable such as in medical and chemical analyzers.
