2005多路換向閥
2005 MULTIPLE DIRECTIONAL CONTROL VALVES
2005多路換向閥主要適用于20-40T汽車起重機液壓系統(tǒng)中，稍加改型，也可運用于其它行走機械的液壓系統(tǒng)中。
2005多路換向閥具有壓力高、流量大、工作可靠等特點。它可根據(jù)主機要求采用20通徑與25通徑閥體組合，滿足執(zhí)行機構(gòu)不同流量的要求，并可采用分合流方式，使執(zhí)行機構(gòu)獲得大的流量（zui大流量230L/min），實現(xiàn)主副卷揚慢速、快速，同時、分別工作不受影響。該產(chǎn)品擁有多種滑閥機能，并采用了負荷傳感技術(shù)，使工作中執(zhí)行機構(gòu)速度不受負載變化的影響，還具有優(yōu)良的微動特性，可實現(xiàn)起重機卷揚點動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.
