The valve represents two hydraulic switches in one valve. The 8/3 way valve is suitable for extending two double acting hydraulic functions. In the absence of current, oil flows from ports A and B to ports A1 and B1. If the magnet is energized, the oil flow is transferred from interfaces A and B to additional consumers A2 and B2 or A3 and B3. The valve is designed to be flanged and extensible. In addition, the valve unit is equipped with pressure protection for lines A and B to enable the transfer of hydraulic overloads in the blocked loop. Because the valve is designed as a slide valve, slight internal leakage is allowed.
