Hydraulic valve device

A valve device, comprising:

• a housing having a plurality of fluid ports and opposite first and second end regions;
• a control spool movable in said housing along a longitudinal axis of said control spool in opposite first and second directions to at least partially connect respective ones of said fluid ports in fluid communication, said control spool having first and second stop surfaces fixed thereon and facing in said first and second directions, respectively;
• and
• first and second counter stops releasably engaging said first and second stop surfaces, respectively, to limit axial movement of said control spool in the first and second directions, respectively, said first and second counter stops being axially adjustable along first and second adjustment axes parallel to said longitudinal axis, being supported by adjustment members extending through and axially movable in said second end region of said housing and having outer ends accessible on an outer surface of said second end region.

A valve device, comprising:

• a housing assembly having a pressure supply fluid port and a utility fluid port;
• a control spool piston movable in said housing assembly in first and second movement directions to at least partially actuate said fluid ports;
• an adjustable stop device restricting a stroke length of travel movements of said control spool piston in the first and second directions, said stop device having a first stop surface facing the first movement direction and a second stop surface facing the second movement direction, said first and second stop surfaces being at a same axial end portion on said control spool piston, said stop device also having first and second counter-stops for engaging said first and second stop surfaces, respectively, said first and second counter-stops being on a same end region of said housing assembly and being positionally adjustable in said housing assembly;
• and
• a recess on said axial end portion of said control spool piston, said second stop surface including a wall surface extending between a base of said recess and an outer periphery of said control spool piston, said second counter-stop having a stepped surface between a shank and an enlarged head portion of a first set screw, said enlarged head portion being engaged in said recess.
