弁体の外周面に径方向に突出する制動部を形成し
たことを特徴とする比例制御弁。 A valve seat is provided between a high-pressure side and a low-pressure side of hydraulic fluid, and a valve element that moves toward and away from the valve seat is arranged on the low-pressure side, and the valve-closing force on the valve element and the operation of the high-pressure side are arranged on the low-pressure side. In a proportional control valve in which the valve opening area between the valve seat and the valve body is automatically adjusted by balancing the valve opening force due to oil, a damper chamber filled with damper oil is placed inside the valve body. A proportional control valve characterized in that a braking portion is formed facing the outer circumferential surface of the valve body and protruding in the radial direction on the outer circumferential surface of the valve body facing the damper chamber.
