A valve flow-directing vessel comprising a sleeve having a threaded installation portion for connection to a receiving member, a plunger movable within the sleeve between a closed position and an opened position, and an orifice insert fixedly attached to the sleeve. A rapid actuating movement is possible and, the action of a high force is also achievable wherein a second piston-cylinder unit and a third piston-cylinder unit. A data memory interface is provided to access the data memory. There may be two positive power supply voltages that are used in powering each memory element. The steerable well bore drilling tool includes an inertial measurement unit to output a measurement used to determine an azimuthal deviation and inclination of the steerable well bore drilling tool during a drilling operation. Further, the present invention also provides hydrogenation catalysts prepared thereof.
