The XYDL*-F15L series multi-way valve is composed of an inlet valve piece, a reversing valve piece and a return valve piece. The oil circuit uses a parallel oil circuit. The valve stem function can be O, Y, N, J, etc. The valve stem reset mode adopts manual or hydraulic reverse direction. In order to meet the requirements of different users, the combination can be arbitrarily increased or decreased. The inlet valve plate has a pilot operated relief valve to control the overall system pressure. A check valve is placed inside the reversing valve to prevent oil from flowing backwards. According to the user's needs, the reversing valve can be equipped with an overload valve or a charge valve at both ends to meet the load requirements of different actuators. The return valve of XYDL*-15 has a pressure output port P1 that can be used in series with other hydraulic components. The valve has a compact structure and a high working pressure, and can realize the advantages of near and remote control of a plurality of actuators. Widely used in hydraulic systems of construction machinery, mining machinery, sanitation machinery and other machinery.
