A solenoid device includes a solenoid assembly (30) including a stator (42, 32, 38) and a coil (36) for generating a magnetic field. An armature structure (14, 16) can move with respect to the solenoid assembly from a closed position, defining a working gap area (62) between the coil and a portion of the armature structure, to an open position in response to the magnetic field generated by the coil. Seal structure (22) is coupled with a proximal end of the armature structure and has a sealing edge (28) to seal with a component when the armature structure is in the closed position thereof. A spring (44) biases the armature structure to the closed position. Under certain operating conditions of the device, pressure is balanced between the working gap area and an area defined adjacent to 1) the sealing edge, and 2) a distal end of the armature structure.
