バルブ装置。[Claims for Utility Model Registration] (1) A pair of opposing ports communicating with the valve chamber of the valve body is provided, a ball-shaped valve body is inserted into the valve chamber, and the valve stem of the valve body is placed over the valve chamber. In a ball valve, a seat ring is inserted into each of the ports, and a stop ring is fitted to the end of each port. A gap is provided in which the seat ring can move forward and backward, step surfaces are provided at two locations on the outer peripheral surface of the seat ring, one on the inside and one on the outside of the port, facing the inside and outside of the port, respectively, and sealing means are provided on both the inside and outside of each step surface. A ball valve characterized in that the ball valve is provided to form two pressure chambers, and each pressure chamber is provided with a pressure medium supply port. (2) In the ball valve according to claim 1,
An opening/closing actuator for the valve body, a main solenoid valve that controls the pressure medium supplied to the actuator, and an auxiliary solenoid valve that controls the pressure medium supplied to each pressure chamber of the seat ring are provided. The control circuit of the valve includes a first timer that drives the main solenoid valve after a certain delay time after driving the auxiliary solenoid valve when the valve is opened, and a timer that drives the main solenoid valve after a certain delay time after driving the auxiliary solenoid valve when the valve is opened, and a timer that drives the main solenoid valve after a certain delay time after driving the auxiliary solenoid valve when the valve is closed. A ball valve device comprising a second timer for returning the auxiliary solenoid valve after a certain delay time.
