  "textContent": "Magnetic latching valves have a housing with first and second ports in controlled fluid communication with one another. Enclosed within the housing is a linearly translatable armature within a solenoid. The armature is movable between open and closed positions and is connected to a poppet valve. A permanent magnet is fixedly seated at a position for magnetically latching the armature in the open position, and a spring is seated with a first end against the poppet valve and a second end against the housing. The spring biases the poppet valve closed when the armature is in the closed position and has a pre-selected spring rate that mechanically relieves pressure if the spring rate is exceeded. The armature is moved to the open position after a pulse of voltage to the solenoid and is in an unpowered state thereafter. Vehicle fuel refueling system are disclosed that include a magnetic latching valve.",
