Abstract
A valve assembly includes a valve body with an interior cavity and one or more supply ports, a control port, and an exhaust port each fluidly connected to the interior cavity. An armature assembly is movable within the interior cavity from a first position to a second position in response to the coil being energized. In some configurations, a regulator body, which is connected to the valve body, has an exhaust passage fluidly connected to the exhaust port. A regulator valve in the regulator body prevents fluid flow out of the exhaust passage when fluid pressure on the regulator valve is at or below a pilot pressure. The regulator valve permits fluid 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 supply port/ports to the control port.
