Abstract
A cage valve includes: a valve body having a fluid inflow path and outflow path; a cylindrical cage, secured within the valve body, having a window connecting to the inflow path and/or the outflow path; a valve plug for opening/closing the window by sliding within the cage along the axial line of the cage; and a self-sealing structure, provided in the cage and/or the valve plug, which improves sealing performance between the cage and the valve plug by bearing pressure of a fluid when the valve plug is in a position wherein the window is fully closed. The self-sealing structure is formed through machining an inner peripheral wall surface of the cage or an outer peripheral wall surface of the valve plug.
