Abstract of the Disclosure A cartridge type sleeve and plunger hydraulic valve is retained in a blind bore along with a biasing spring by a closure plug. Spaced transverse passages intersecting the bore are either separated or connected depending upon whether the plunger is either shifted by the spring bias or by fluid pressure overcoming the spring bias. An elastomeric seal eliminates leakage when the valve is in closed position. To insure against accidental fall out of any loose parts when the valve is disassembled under difficult working conditions, as in mines, O-rings are utilized as retainers for the spring and other parts. - i -
