    • 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).

    • A plurality of valve assemblies (10) are provided to a base (11), and an air-supply flow path for supplying compressed air to each valve assembly is formed in the base. A main flow path communicating with the air-supply flow path (21) and communicating with a pilot air-supply flow path (44) is formed in an air supply block. When the compressed air is supplied to the air-supply flow path and the pilot air-supply flow path from the main flow path, a manifold solenoid valve becomes an internal pilot type. An external pilot flow path communicating with the pilot air-supply flow path is formed in an external pilot block, and when the external pilot block is provided, communication between the main flow path and the pilot air-supply flow path is shut off, and the manifold solenoid valve becomes an external pilot type in which the pilot pressure is supplied from the external pilot flow path.
    • 多个阀组件(10)设置在基座(11)上,并且用于将压缩空气供应到每个阀组件的供气流路形成在基座中。 在供气块上形成有与供气流路(21)连通并与先导供气流路(44)连通的主流路。 当压缩空气从主流路供给到供气流路和先导供气流路时,歧管电磁阀成为内部先导式。 在外部的先导块形成有与先导供气流路连通的外部先导流路,在设有外部先导块时,切断主流路与先导供气流路之间的连通, 歧管电磁阀成为从外部先导流路供给先导压的外部先导式。
