Hydraulic control valve for agricultural implements

摘要

A hydraulic valve having a main body in which is formed a pressurized-fluid inlet opening; a first conduit communicating hydraulically with a user device; a second conduit communicating hydraulically with the user device; and at least one spool for regulating pressurized fluid flow to and from the user device; the spool having a longitudinal axis, and the position of the spool being regulated by an actuating device; the hydraulic valve being characterized in that the actuating device has a guide member for preventing the spool from rotating about the axis; the actuating device also having a cable, e.g. a Bowden-type cable, for moving the spool in two opposite directions defined by the longitudinal axis.
