A valve control device ( 1 ), in particular for control pods or similar equipment used in the mining and/or production of mineral oil/natural gas, comprises a valve housing ( 2 ), in which hole or boring sections ( 3, 4, 5, 6 ) are arranged, and a valve slide ( 7 ) movable relative to the hole sections, with at least a first and a second flow hole ( 8, 9 ) for the alternative connection of a feed line ( 10 ) from a fluid pressure hose with at least one actuator ( 11 ) or of the actuator to a return line ( 12 ) for leading the fluid away, wherein in each case one of the connections is made and the other is interrupted. To improve such a valve control device in that with only slight and economical constructional modifications with retention of all the advantages of known valve control devices, a substantial reduction in the leakage flow is facilitated or even almost completely suppressed, at least first and second valve elements ( 16, 17 ), which in the closed position ( 15 ) can be pressed onto a valve seat ( 13, 14 ) formed especially at a hole section ( 4, 6 ), are laterally assigned to the flow holes ( 8, 9 ), wherein in the connection position of the first flow hole ( 8 ) the second valve element ( 17 ) is in the closed position ( 15 ) and in the connecting position of the second flow hole ( 9 ) the first valve element ( 17 ) is in the closed position ( 15 ) each pressed onto the respective assigned valve seat ( 13, 14 ) in its closed position ( 15 ).
