    Abstract: A double-solenoid directional control valve comprising a valve body and a valve spool within the valve body, where the valve spool is configured to move within the valve body between a first position, a second position and a third position, where the third spool position lies between the first and second spool positions. In certain embodiments, the spool is maintained in the first and third positions by energizing at least a first or a second solenoid actuator, and where the spool is maintained in the second position by de-energizing both solenoid actuators.

    Abstract: A hydraulic valve with electropneumatic activation includes an air inlet that receives pressurized air from an air compressor and directs it into a line of the cylinder. The line is connected to an extension line attached to a solenoid extension valve that allows or blocks the passage of pressurized air from the extension line to a rear line. The rear line is attached to the rear chamber of the cylinder and connected to a retraction line attached to a solenoid retraction valve that allows or blocks the passage of pressurized air from the retraction line to an anterior line, which is attached to the front chamber of the cylinder. Thus, the passage of pressurized air is managed according to the desired movement of the stem of the hydraulic actuator. The pneumatic tubes are eliminated and electropneumatic valves are replaced by solenoid valves incorporated into the cylinder of the hydraulic valve.
