Remotely actuated, reversible drain valve

A remotely actuated, reversible valve for draining fluid from the drain outlet of a fluid reservoir comprising:

• a valve body having a manifold defining a plurality of longitudinal valve portions, each defining a longitudinal fluid passageway, said valve body including a transverse section defining a transverse passageway in communication with each of said longitudinal passageways, connecting means adjacent the distal end of said transverse section for providing fluid communication between said transverse passageway and said fluid reservoir, each said valve portion including
• a longitudinal section having a pair of substantially identical connecting means located at the opposite ends of said longitudinal section;
• an outlet sleeve joined with the connecting means at one end of said longitudinal section, said outlet sleeve having an annular sealing surface disposed adjacent said one end, said outlet sleeve defining a longitudinal outlet port;
• a closure member having a portion operatively connected to the connecting means of the other end of said longitudinal section, said closure member cooperating with said manifold to define a valve chamber;
• a valve member disposed within said longitudinal section for longitudinal motion between an open position and a closed position, said valve member including a generally cylindrical sealing head for forming a seal with said sealing surface when said valve member is set to said closed position;
• a biasing spring between said closure member and said sealing head, said biasing spring cooperating with fluid in said valve chamber to urge said valve member to the closed position;
• and
• cable means extending longitudinally through said closure member and connected to said valve member for withdrawing said sealing head from said sealing surface to said open position whereby each said valve portion is independently operated to selectively direct fluid from said outlet port.
