DYDL5*-F20L series multi-way valve is composed of an inlet valve piece, a reversing valve piece and a return valve piece. The oil circuit can be connected in parallel. Stem center function: O、Y、N、J, etc. And the spool returning of valve stem adopts manual control or electrohydraulic control reversing, which can increase or decrease in combination to meet different customers’ requirements. The inlet valve piece has a pilot relief valve to control the overall system pressure. The inside of reversing valve piece install check valve to prevent oil backflow. According to user needs, both ends of inlet valve piece installed overload valve or filling oil valve to meet the needs of different actuator load. DYDL5*-F20L’s return valve piece has pressure outlet P1 which can be used in series with other hydraulic components. The valve has the advantages of compact structure, high working pressure and can realize near and remote control of multiple actuators. Widely used in engineering machinery, mining machinery, sanitation machinery and other hydraulic system of other machineries.
