A directional hydraulic valve has a feed chamber, two user connection chambers, two discharge chambers connected to a discharge tank, and a control spool. The hydraulic valve also has two intermediate chambers which are connected together, each adjacent the feed chamber and one of the user connection chambers. The intermediate chambers are adapted to be places in fluid communication with a flow regulating device which regulates the flow of fluid originating from the feed source and directed to the feed chamber in relation to the pressure value of the fluid present in the intermediate chambers. The valve has a valve mechanism for connection between the intermediate chambers and one of the discharge chambers.
