A solenoid valve includes a housing defining an interior, a coil disposed in the interior, and an armature disposed in the interior and moveable between a first position and a second position during energization of the coil. A stationary member is fixedly coupled to the housing and has an inner surface defining a central bore, a first detent, and a second detent. A moveable member is disposed in the central bore, defines an aperture, and is moveable with the armature relative to the stationary member between the first and second positions. A biasing member is disposed in the aperture, and a locking member is biased by the biasing member toward and is engageable with the stationary member in the first detent to hold the moveable member in the first position and is engageable with the stationary member in the second detent to hold the moveable member in the second position.
