The DL*-F20L series multi-way valve is composed of an inlet valve piece, a reversing valve piece and a return valve piece. The oil return body of the DL1-F20L series multi-way valve has a pressure output port and can be used in series with other hydraulic components. The valve has the advantages of compact structure, large flow, high working pressure, good performance, reliable operation, and the advantages of near and remote control of multiple actuators. Widely used in hydraulic systems of construction machinery, mining machinery and other machinery.
◆ Built-in check valve: Each joint commutator has a built-in check valve to prevent oil backflow
◆ Built-in relief valve: Pilot-operated relief valve in the oil body to control system pressure
◆ Oil circuit form: can realize parallel, series or series-parallel composite oil circuit
◆ Additional valve: Both ends of the commutator, add overload valve or charge valve as needed
◆ Valve body structure: sheet structure, any combination of 1~8
◆ Valve stem median function: A, Z, O, Y, etc.
