せるべく構成した比例制御弁。In a proportional control valve that controls the flow rate by changing the gap between the valve seat ■ and the needle valve ■, which has a valve seat ■ inside the valve body ■, the needle valve ■, the valve stem ■, the bearing part ■, the male thread ■, and the end bushing. The parts ■' are sequentially formed by one shaft body, the center part of the rotor ■ of the motor is made into a female thread, and is fitted with the male screw ■, and the rotor ■ is moved in the axial direction by the bearing metal ■ and the end bearing metal 0. A proportional control valve configured to prevent rotation of the valve stem (■) by a pin [phase], and to rotate the rotor (■) by energizing the fixed coil (■) of the motor.
