    • PURPOSE: To obtain an inexpensive compound control valve by constructing said valve normally regardless of providing a valve for attachment by providing a loading valve downwardly against a by-pass passage 18 for a normal compound control valve and by opening and closing said loading valve in response to the actuation of said valve for attachment.
      CONSTITUTION: A compound control valve 11 is provided slidably on its valve body 12 such that spools 15W17 connected respectively to prescribed actuators are possible to slide and pressure oil is supplied from a pump 14 to an inlet room 13. Further a valve 34 for attachment is provided on this compound control valve 11. In this instance, a loading valve 51 is mounted downwardly against a by-pass passage 18 of the compound control valve 11. A pilot room 57 of the same valve 51 is connected to a room 66 of a pilot change-over valve 61 provided on the valve 34 for attachment via a pipe 58. And, simultaneously with the actuation of the valve 34, the loading valve 51 is closed by the change-over valve 61, being kept in a loading state, and at the time of the closed center of the valve 51, said valve 51 is kept in a unloaded state.
