The SQEDLG*-F15L Series Multiplex valve is composed of inlet valve plate, commutator valve plate and return oil valve sheet. The oil road adopts parallel oil road. Stem function has a, O, Y and so on, stem reset mode using manual or gas-controlled commutative, in order to adapt to the requirements of different users, can be arbitrarily increased or decreased combination. The inlet valve sheet comes with a pilot overflow valve to control the entire system pressure. A one-way valve is arranged inside the commutator valve plate to prevent oil reflux. According to the needs of users, the two ends of the commutator valve can be fitted with overload valve or filling valve to meet the load needs of different actuators. SQEDLG*-F15L's return valve sheet comes with a pressure output port P1, which can be used in series with other hydraulic components. The valve has the advantages of compact structure, high working pressure, good performance and reliable operation, and can realize the near and remote control of multiple actuators. Widely used in hydraulic systems for construction machinery, mining machinery, sanitation machinery and other machinery.
