ZT系列多路换向阀/ ZT SERIES MULTIPLE DIRECTIONAL CONTROL VALVES RODE
用途与特征/APPLICATIONS&FEATURES
ZT-L12系列多路换向阀,是一种中高压整体式多路换向阀。其结构紧凑,体积小,针对安全阀的结构性能也进行了特殊设计。该阀采用并联油路,并设计有压力输出口与其他液压元件相连接提供动力源。滑阀技能有O、A、Y、P、K、Q等多种机能供客户选择,操纵形式有单控、双控两种结构。广泛应用于随车吊、高空作业车、矿山钻机等工程机械的液压系统中。
ZT-L12 series multiple directional control valves road, is a kind of in high pressure and multi-way directional valve. Its compact structure, small volume, according to the structure of the relief valve performance has also carried on the special design. This valve USES the parallel lines, and design pressure lose exports and other hydraulic elements connected to provide power supply. Rotary piston skills have O, A, Y, P, K, Q and so on many kinds of function for the customer to choose, manipulate form have single control, double charged with two kinds of structure. Widely used in the accessory crane, aerial work car, mining rig and other construction machinery of the hydraulic system.

备注/NOTE:
ZT整体阀的优点:
ZT whole the advantages of valve:
1. 采用整体式,密封性能好,加大油路通道,使压力损失减小。
Adopt and, sealed performance is good, increase oil line channel, the pressure loss.
2. 采用直动式安全阀,启闭性能好,不会堵塞,回转机构受到外界作用而超载时,过载阀将灵敏的开启卸荷,保持系统时刻处于安全状态。
The e-style relief valve, open the performance is good, not jam, rotary mechanism by the outside world role and the overload, overload valve will sensitive open unloading, keep the system in a safe state time.
3. 具有过桥功能,可利用过桥阀体或外接油口向其它机构提供油源。
Has the bridge function, can use across the bridge body or external oil to other organizations with mouth oil source.
