Abstract: A tool for unseizing and/or lubricating a valve having a protruding valve stem on an exterior periphery. The tool possesses a hollow tubular member, having at one end thereof an open, hollow, cylindrical flexible member adapted to be placed over and contain therewithin a portion of the valve stem. A circumferential tightening member, encircling one end of the flexible member, is provided, to permit the flexible member to sealingly engage the valve stem about the outer periphery thereof when the flexible member is placed over the valve stem. The tool further possesses a fluid inlet port, situated along a length of the tubular member, in fluid communication with an interior of the tubular member, and a pressurized fluid inlet port likewise in fluid communication with the interior of the tool.

Abstract: A grease tool lubricates a valve having an actuator assembly for moving a valve element of the valve. The tool has a housing with a piston carried in a bore. The housing is open for inserting and sealing a portion of the actuator assembly into the bore. A fill port in the housing allows grease to be introduced into the bore. A piston rod joins the piston and has external threads engaging internal threads of the housing, so that rotating the piston rod causes the piston to move axially. A lever is mounted to the housing for imparting rotation to the housing. A lock pin extends through a side wall of the housing to engage the actuator assembly to cause the actuator assembly to rotate in unison with the housing.
