Abstract

There is described a control device for actuating a pair of hydraulic spool valves arranged, for example, side-by-side in a valve block. The device includes a two-arm actuating member such that when the actuating member is pivotted about the axis of one of the arms the other arm operates its associated valve and vice versa, the valves being operatively connected to its respective arm through a follower.
