Abstract
A valve including a valve assembly and a solenoid assembly. The solenoid assembly is coupled to the valve assembly to actuate the valve assembly. The solenoid assembly includes a movable armature engaged with a poppet of the valve assembly. A plate spring having a spring force is positioned between the valve assembly and the solenoid assembly that is configured to bias the valve member of the poppet into engagement with a valve seat. 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 to proportionally control an amount of flow that is permitted through the valve assembly.
