Z系列多路换向阀

　　Z系列多路换向阀是由多个换向阀和安全阀及各种附加阀组合而成。它具有工作压力高、结构紧凑、安全阀性能好、可靠性高、不易外漏、通用性好等特点。它主要用于ZL40以下装载机及多功能装载机、小型挖掘机等工程机械的液压系统中，也用于起重运输机械、矿山机械、农业机械或其它机械的液压系统中，实现多个执行机构的集中控制。
　　该系列多路换向阀每连都带单向阀。根据用户需要，可在任一工作腔和回油腔之间安装过载阀或补油阀。能够组成并联、串联或串并联复合油路，并有多种滑阀机能、定位、复位方式及控制方式，也可利用过桥阀体或外接油口向其它机构提供油源, 广泛地满足了不同主机的需要。
　　The Z series multiple directional control valves consist of several directional valves, safety valves and some additional valves with such characteristics as high in working pressure, compact in structure, leak outside uneasy, good commonality and high performance of relief valve. They are mainly used in hydraulic systems of engineering machinery such as loaders with below model ZL40 loaders, multifunctional loaders and small excavators. The valves can also be used in hydraulic systems of mining machinery, lifting transportation machinery, agricultural machinery and other machinery to carry out integrated control over several actuating mechanism.
　　The Z series multiple directional control valves have a check valve in each piece. On demand by users, the overload valve or make up valve may be installed between any work chamber and returning chamber. The circuit can be of parallel type, serial type or composite.There are several spool functions, positioning and returning modes and control modes. Oil may be also fed to other mechanism through interim valve block or external port, hence to meet a variety of different main machines needs.
