2005多路换向阀
2005 MULTIPLE DIRECTIONAL CONTROL VALVES
2005多路换向阀主要适用于20-40T汽车起重机液压系统中，稍加改型，也可运用于其它行走机械的液压系统中。
2005多路换向阀具有压力高、流量大、工作可靠等特点。它可根据主机要求采用20通径与25通径阀体组合，满足执行机构不同流量的要求，并可采用分合流方式，使执行机构获得大的流量（zui大流量230L/min），实现主副卷扬慢速、快速，同时、分别工作不受影响。该产品拥有多种滑阀机能，并采用了负荷传感技术，使工作中执行机构速度不受负载变化的影响，还具有优良的微动特性，可实现起重机卷扬点动2-3mm的操作。
The 2005 multiple directional control valve applies to 20-40T truck crane hydraulic system,with a little modification,can also be applied to the hydraulic system of other machines running.
The 2005 multiple directional control valve is characterized by high pressure ,flow,reliable work,and so on.It can be used in accordance with requirements of the host 20 and 25 Path body combinations to meet the executive body of different flow requirements,and adopt a combined approach,so that the implementing agencies to obtain large flow（the largest flow230L/min）. Hoist the main achievement of the Deputy slow,fast,at the same time,each work is not affected .The product has a multi-function valve slide,and adopts a load sensing technology so that the work of the executive body from the loading speed of change,but also have excellent micro-features can be a crane,winch to move 2-3mm operation.
