ABSTRACT:
A high capacity direct acting three-way bistable power operated valve is connected to control operation of an hydraulically operated magazine sprinkler control valve. The three-way bistable valve controls application of high pressure sea water and includes a slidable hollow valve spool having one end that is selectively seated upon and sealed against a valve seat in an inlet chamber, and having an intermediate spool portion connected to a common valve port. The other end of the hollow spool extends into an outlet chamber and is sealed against a valve seat therein when the first end of the spool is displaced from its valve seat and vice versa. Input pressure on the spool can be completely balanced or arranged to enhance sealing of the spool. The valve spool is axially shifted and latched either by a motor operated cam circuit arrangement or by driving and unlatching solenoids.
