ZDa*-F15L series multi-way valve belongs to medium and high pressure integral multi-way reversing valve, parallel circuit. The valve is pre-configured with a pressure output port, and the P1 port can be used in series with other hydraulic components after the screw is plugged. The valve has the advantages of compact structure, small volume, high working pressure, good performance, reliable work, convenient use and maintenance, and the like. Widely used in hydraulic systems of small construction machinery, mining machinery, sanitation machinery and other machinery.
◆ Built-in check valve: The valve body has a built-in check valve to prevent oil from flowing backwards.
◆ Built-in relief valve: valve body built-in relief valve to control system pressure
◆ Oil circuit form: parallel oil circuit
◆ Valve body structure: integral structure, with 4, 5, 6 joint selection
◆ Stem center function: A, O, Y, etc.
