A valve assembly includes a housing, an actuator, a plunger, a cover, a valve body, and a manual override unit. The actuator is received within the housing and is disposed between a first annular wall and a second annular wall. The plunger is movably disposed within a plunger cavity that is defined by the base and the second annular wall. The cover is disposed on the housing. The valve body is connected to the housing. The valve body has an end wall that defines an outlet port, an annular wall that axially extends from the end wall and defines an inlet port, and a flange that extends from the end wall and engages the cover. The manual override unit is operatively connected to the plunger.
