Abstract
A valve assembly includes a valve body with an interior cavity and a primary supply port, a secondary supply port, a control port, and an exhaust port each extending to the interior cavity. An armature assembly is configured to move within the interior cavity from a first position to a second position when the coil is energized. A regulator body is operatively connected to the valve body and has an exhaust passage positioned at the exhaust port. A regulator valve in the regulator body is configured to prevent flow out of the exhaust passage when fluid pressure on the regulator valve is at or below a pilot pressure and permit flow out of the exhaust passage when fluid pressure on the regulator valve is greater than the pilot pressure. The valve body is configured to provide fluid from the secondary supply port to the control port.
