Abstract
In the case that a lift amount of a second valve body for controlling a small flow rate is equal to or less than a predetermined amount, a pilot passage is closed by a pilot valve body, and a first valve port is closed by a first valve body for controlling a large flow rate, thereby taking a small flow rate control state in which a flow rate is controlled in correspondence to the lift amount of the second valve body, and in the case that the lift amount of the second valve body goes beyond the predetermined amount, the pilot valve body is moved up in conjunction with an upward movement of a valve shaft so as to open the pilot passage, thereby taking a large flow rate control state in which the first valve body opens the first valve port on the basis of this.
