Load Sensitive Multiway Reversing Valve QFZMG32H-O-DK-A
Uses and FeaturesQFZMG32H full-load sensitive proportional multi-way directional valve is an advanced product developed by our company for large-tonnage crawler cranes and dynamic compactors, with the same technical level as Rexroth M7-25, and can fully meet the needs of localization of the host hydraulic system. QFZMG32H full load sensitive proportional multi-way directional valve adopts LUDV system. The meaning of LUDV is the flow distribution independent of the load pressure, and each LUDV pressure compensator is related to the highest pressure. If there is insufficient flow in the LUDV system, that is, the oil pump cannot provide enough flow to operate the actuators at the required speed, the actuators will reduce their movement speed proportionally.One of the major advantages of the LUDV system is that if the implementation of the components of the oil shortage, there will be no implementation of the components to stop working. The valve is equipped with secondary pressure safety valve and flow load pressure compensator, high repeatability and low hysteresis. Hydraulic proportional control, can be adjusted by the spool stroke limit flow.
