A solenoid valve (100) with an integrated check valve functionality is provided. The solenoid valve (100) comprises first, second, and third ports (101, 102, 103). The solenoid valve (100) further comprises an armature (140) movable between a first position in which fluid flow from the second port (102) to the third port (103) is blocked and fluid flow from the first port (101) to the third port (103) is unblocked and a second position in which fluid flow from the second port (102) to the third port (103) is unblocked and fluid flow from the first port (101) to the third port (103) is blocked until fluid pressure at the first port (101) exceeds fluid pressure at the third port (103) by a predetermined amount of fluid pressure to thereby provide the check valve functionality. The check valve functionality is integral to the armature (140). The solenoid valve (100) also comprises an energizeable solenoid (150) for, when energized, moving the armature (140) from the first position to the second position.
