ABSTRACT:
The valve of the invention is provided with a movable slide valve operable to open a first flow passage between a supply duct, which connects a source of fluid under pressure with the valve, and a utilization duct, which connects the valve itself with the utilizer, and a second flow passage between this utilization duct and a discharge duct; the slide valve is in equilibrium between a resilient force generated by a spring which acts on it and the force, in the opposite direction, generated by the fluid pressure which is supplied to a control chamber and the discharge flow cross section of which is controlled by a valve member operated by an electromagnet.
