A valve apparatus includes a body including a first wall and a second wall, a chamber defined within the body, a valve member positioned in the chamber, a first conduit defined within the body to extend through the first wall and configured to be in fluid communication with the chamber and a source of fluid, a second conduit defined within the body to extend through the first wall and configured to be in fluid communication with the chamber and a source of vacuum pressure, and an actuator operatively connected to an end of the valve member extending through the body from the chamber. The actuator may position the valve member within the chamber to selectively form a first flow path with the first conduit that extends through the chamber and the second wall, and a second flow path with the second conduit that extends through chamber and the second wall.
