A proportional solenoid-controlled valve provides for precise control of fluid flow using a flat spring and a damper. The flat spring is three-lobed and is constrained on its outer diameter in one of six degrees of freedom. The damper has three outer lobes which are compressed between the armature assembly and the valve body. A spring-loaded seal configuration having an annular elastomer seal compensates for dimensional instability of the elastomeric seal material and the armature assembly.
