said actuator includes a plurality of castellations formed adjacent the upper marginal end of said sleeve, and a plate member having a plurality of projections formed thereon for being received within the intervening space between said castellations;
shaft means for rotating said plate member and thereby rotating said sleeve from one into another flow position;

Abstract
A full opening sleeve valve device with check valve for controlling fluid flow through a line pipe or the like. The valve device has a housing, and a flow passageway extends through the housing and terminates at opposed ends thereof. The opposed ends of the housing passageway can be connected to the confronting ends of a pipe line. A bore extends through the housing and a flow control sleeve is rotatably received within the bore and sealingly engaging the peripheral wall surface of the bore. The sleeve has opposed ports that can be selectively rotated into registry with the flow passageways to align the ports with the passageway whereupon unrestricted flow can occur through the valve device. The check valve is a movable wall section of the sleeve and forms a closure member for a sleeve port and cooperates with the bore to form a check valve. When the ports are aligned with the passageway, the check valve is moved to the opened position when flow occurs in one direction and is moved into the closed position when flow occurs in an opposite direction. An actuator is provided for rotating the sleeve between an open and closed position wherein flow in either direction is precluded.
