Abstract

PURPOSE:To simplify a piping system by providing three liquid draining passages each having a solenoid valve on a cylinder in which a main valve is slidably inserted. CONSTITUTION:Three liquid draining passages 11, 12a, 12b are provided in a cylinder 9 in which a main valve 1 is slidably inserted. These three passages are connected to a liquid pressure chamber 5 on the back of the main vale 1 in order in the moving process of the main valve 1 from its closed position to the opened position, and solenoid valves V1, V2 are provided on these liquid draining passage 11, 12a, 12b. Hence, by individually carrying out the opening/ closing operation of the solenoid valves V1, V2, it is possible for a single valve body to perform the changeover of flow rate in three stages of large flow rate, medium flow rate, and small flow rate, thereby, without need for providing plural valves simplifying a piping system.
