The solenoid valve assembly includes a retainer attached to the seat disc holder such that the retainer and the seat disc holder form a plunger head receiving cavity that houses a head of the plunger. The solenoid valve assembly includes a seat disc attached to the seat disc holder. The solenoid valve assembly includes an electromagnetic coil energizable to cause the solenoid valve assembly to move from a closed configuration in which the seat disc sealingly engages the valve seat and an open configuration in which the seat disc is disengaged from the valve seat.
