A cartridge control valve includes a valve body that defines an inlet passage separated from an outlet passage by a flat valve seat. A solenoid is attached to the valve body. A valve member has one end positioned in the valve body and an other end attached to the solenoid. The valve member has an annular knife edge valve surface located between the one end and the other end. The valve member is moveable from a first position to a second position by energizing the solenoid. The annular knife edge surface is away from the flat valve seat to open the inlet passage to the outlet passage when the valve member is in one of its first position and its second position. The annular knife edge valve surface is seated against the flat valve seat to close the inlet passage to the outlet passage when the valve member is in the other of its first position and its second position.
