Claim 12:
13. A valve comprising:
a valve assembly that is configured to selectively permit communication between a fluid inlet and a fluid outlet, the valve assembly including:
a hollow valve retainer having a first port that is configured to communicate with the fluid inlet, a second port that is configured to communicate with the fluid outlet, and a valve seat between the first port and the second port;
a movable poppet located within the valve retainer, the poppet including a valve member that is configured is engage and disengage with the valve seat to permit fluid to travel from the fluid inlet through the first port to the second port, and then to the fluid outlet;
a first diaphragm located proximate a first end of the valve retainer; and
a second diaphragm located proximate an opposing second end of the valve retainer; and

a solenoid assembly coupled to the valve assembly that is configured to actuate the valve assembly to permit the communication between the fluid inlet and the fluid outlet, the solenoid assembly including a movable armature engaged with the poppet, a first bushing that surrounds the armature, a plate spring positioned between the armature and the first bushing, and a solenoid coil that is configured to move the armature and the poppet to permit the communication between the fluid inlet and the fluid outlet,
wherein the plate spring is configured to bias the valve member of the poppet into engagement with the valve seat of the valve retainer, the plate spring having a spring force,
the solenoid coil is configured to move the armature and the poppet based a voltage or current that is applied to the solenoid coil, and
based on the spring force of the plate spring and the voltage or current that is applied to the solenoid coil, the solenoid assembly is configured to control a distance that the valve member moves relative to the valve seat of the valve retainer to proportionally control an amount of flow that is permitted through the valve assembly.
