制御弁。[Claims for Utility Model Registration] 1. In a proportional electromagnetic control valve that controls the position of a spool in a valve body by balancing the output of a proportional solenoid with a spring force, the side of the proportional solenoid connected to the valve body. An end cap is provided at the opposite end of the proportional solenoid, and a screw member that is always screwed into a predetermined position in the moving direction of the movable core of the proportional solenoid is screwed into this end cap, and a small diameter rod is attached to the tip of this screw member. A spring seat having a diameter larger than the thread diameter of the screw member is fitted and held in the rod so as to be relatively movable in the moving direction of the movable core, and a compression spring is inserted between the spring seat and the movable core. A proportional electromagnetic control valve characterized in that a required number of spacers for setting a spring force are inserted between the spring seat and the screw member by inserting them into the rod. 2. In a proportional electromagnetic control valve that controls fluid pressure by balancing the output of a proportional solenoid with the acting force of a valve body such as a valve body within the valve body, the side opposite to the side of the proportional solenoid connected to the valve body. An end cap is provided at the end of the proportional solenoid, and a screw member that is always screwed into a predetermined position in the moving direction of the movable iron core of the proportional solenoid is screwed into the end cap, and a small diameter rod is provided protruding from the tip of the screw member. A spring seat having a diameter larger than the screw diameter of the screw member is fitted into the rod so as to be relatively movable in the moving direction of the movable core, and a compression spring is interposed between the spring seat and the movable core. . A proportional electromagnetic control valve characterized in that a required number of spacers for setting a spring force are inserted between the spring seat and the screw member and inserted into the rod.
