ABSTRACT:
A reversible drain valve that is remotely actuated is disclosed. The valve includes a longitudinal fluid passageway having a pair of identical connecting means located at opposite ends. An outlet sleeve having a sealing surface is joined with either of the connecting means. A closure member is joined with the other connecting means and cooperates with the longitudinal passageway to form a valve chamber. A cable actuated valve member is urged to a closed position against the sealing surface with the use of a biasing spring and fluid collected in the valve chamber.
