Abstract
A pressure reducing and regulating valve having a container with a plurality of openings for moving between first and second flow plates having a plurality of inlet ports and a plurality of outlet ports for providing multiple flow paths through the valve for providing maximum flow with a short regulating stroke. The valve may be actuated by a combination of a manual screw adjustment and/or a powered operated overdrive which utilize drive gear to provide a failsafe operation as the power overdrive maintains the regulated pressure even if the pilot source fails. Valve means and stop means control the extent of travel of the adjustment screw. An integral pilot operated bypass valve may be utilized for remotely controlling the actuation of the valve.
