ABSTRACT:
In a multiple orifice body fluid flow restrictor valve having a flow passageway between its ports opened and closed by superposed multiple orifice discs controlled by a yoke connected with one of the discs and having a yoke stem projecting outwardly of the valve body through a valve body top a sleeve cage loosely nested by a valve body counterbore intersects the passageway and surrounds the yoke and discs. The valve body top and sleeve cage forms a unit easily removed from and reinserted into the valve body for repair or replacement of worn valve components without disconnecting the valve from a flow line. The sleeve cage is releasably secured to the valve top in a manner permitting angular rotation of the valve top relative to the valve body and sleeve cage while the latter is nonrotatably secured within the valve body in an axially slidable manner relative to the valve body while threadedly connecting or releasing the valve body top to or from the valve body.
