these valves consist of a small size but high performance electro-hydraulic proportional pilot
relief valve and reducing valve with relief function. the valves c ontrol the system pressure
proportionally through a controlled input voltage. moreover, a good response speed
in reducing the pressure even at a large load capacity can be obtained with the relief function of the valves.
