The solenoid valve includes a valve body (2) having a fluid path therethrough (4 to 14), a valve closure member (18) cooperating with a valve seat (16) to control the flow of fluid therethrough, and a two stage solenoid device (22-74) operable in response to first and second energizing signals to move the valve closure member to first and second different positions with respect to the valve seat thereby to effect first and second different flow rates through the valve. |
