1. A solenoid valve assembly, comprising:
a valve body comprising a valve seat and defining an inlet and an outlet in fluid communication with one another;
a cartridge mounted to the valve body;
a plunger slidably received by and configured to abut the cartridge;
a seat disc holder slidably received by the cartridge;
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;
a seat disc attached to the seat disc holder; and
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 prevents fluid flow from the inlet to the outlet to an open configuration in which the seat disc is disengaged from the valve seat and enables fluid flow from the inlet to the outlet.
