A solenoid valve includes a housing that establishes a supply port, a control port, and an exhaust port. A fluted bushing is statically affixed within the housing and a poppet slides within the bushing. The poppet is movable between a de-energized configuration wherein flow is prohibited between the control port and the exhaust port, and permitted between the control port and the supply port, plural partially energized configurations wherein flow is permitted between the supply port and the control port, between the control port and the exhaust port, and between the exhaust port and the supply port, and a fully energized configuration wherein flow is prohibited between the control port and the supply port and flow is permitted between the control port and the exhaust port.
