1. A full opening sleeve valve device for controlling fluid flow comprising:

  • a housing, a flow passageway though said housing terminating in opposed ends, means by which the opposed ends of the passageway can be connected in a pipe;

    a bore extending through said housing transversely respective to said flow passageway and forming confronting passageway ends that terminate at and communicate with said bore, a flow control sleeve rotatably received within said bore and sealingly engaging the peripheral surface of the bore and thereby preventing flow through said passageway;

    opposed ports in said sleeve diametrically opposed to one another that can selectively be rotated into registry with said flow passageway to thereby align said ports with said confronting passageway ends whereupon unrestricted flow can occur through the valve device;

    check valve means for one of the sleeve ports arranged whereby when said sleeve is rotated to align said sleeve ports with said passageway confronting ends, said check valve can be moved into the opened position when flow occurs in one direction through said passageway, and said check valve means can be moved into the closed position when said sleeve is rotated to reverse the relationship of the sleeve ports respective to the confronting passageway ends and thereby effect flow in an opposite direction;

    an actuator for rotating said sleeve to bring either of the sleeve ports into alignment with either of the confronting passageway ends and thereby place the valve in either of several alternate flow positions including an open and closed position;

    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;

    an arcuate stop means on said body, said arcuate stop means has opposed ends, and stop means on said sleeve for abuttingly engaging the opposed ends of said arcuate stop means when said sleeve is rotated to selectively position the sleeve ports respective to the passageway confronting ends.
