A module solenoid valve (14) includes a valve body (16) defining an inlet opening (22) and an outlet opening (20). The valve body includes a valve seat (18) at a distal end thereof. A valve member (24) controls flow of fuel through the outlet opening. A movable armature (26) is coupled with the valve member such that movement of the armature moves the valve member between a closed position and an open position. A stator (38) is associated with the armature. An electromagnetic coil (36) is associated with the stator and armature for causing movement of the armature towards the stator. A spring (32) biases the armature and thus the valve member to the closed position. The spring provides a spring force that is greater than a first, normal hydrostatic force applied to the valve seat, but less than a second, overpressure hydrostatic force applied to the valve seat. |
