Load Sensitive Multiway Reversing Valve QFZMG14H-3Y-3C-3C-DK

Uses and FeaturesThe QFZMG14H-00 load-sensitive multi-way directional valve adopts the LUDV system, which distributes the flow between the various directional valves according to the demand, regardless of the load pressure. The compact superposition valve plate design can be combined into different valve groups to meet the requirements of different equipment. Through the main relief valve, LS relief valve and secondary relief valve in a variety of ways to protect the system, there are manual, hydraulic control, electric ratio and other manipulation methods to choose from, used in truck cranes, truck cranes, small excavators and other construction machinery and equipment. Performance parametersPath(mm)Nominal pressure(Mpa)nominal flow(L/min)Allowable back pressure(Mpa)1431.51752 

Load Sensitive Multiway Reversing Valve QFZMG15H-5-SANY

Uses and FeaturesQFZMG15H type full load sensitive multi-way directional valve is one of the latest products developed and produced by our company. Its excellent full-load feedback function can realize the system load sensing follow-up control, reduce the load of the pump, reduce power consumption and system heating, so that the control accuracy of the construction machinery can be improved in an all-round way, and the energy loss is minimized. It can be called a high-precision control energy-saving product.QFZMG15H type full load sensitive multi-way directional valve, with excellent "valve pressure compensation" function, each working oil port can be according to the requirements of the host actuator, to provide the corresponding flow, and to ensure that the working speed of the actuator is not affected by load changes, and has excellent micro-performance.The QFZMG15H type full load sensitive multi-way directional valve is operated in various ways. With manual, hydraulic proportional, electro-hydraulic proportional control of a variety of control methods.The development of QFZMG15H-type full-load sensitive multi-way directional valve adapts to the development trend of domestic construction machinery industry, and its performance has reached the technical level of M4-15-type multi-way directional valve produced by Rexroth abroad. It is an ideal product for the localization of host hydraulic system. Performance parametersPath(mm)Nominal pressure(Mpa)nominal flow(L/min)Allowable back pressure(Mpa)Pilot control pressure(Mpa)153815020.5~2.4

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. Performance parametersPath(mm)Nominal pressure(Mpa)nominal flow(L/min)Allowable back pressure(Mpa)Pilot control pressure(Mpa)324060020.6~2.4
