● 用途与特征 APPLICATION AND FEATURES
 ZT-L20多路换向阀是我单位自主设计开发的一种中高压整体式多路换向
阀。可按客户要求在阀上设溢流阀、过载阀、单向阀、补油阀等。溢流阀可调节
系统压力、过载阀控制单个油腔工作压力，单向阀防止油液倒流，换向阀滑阀机
能有A、O、Y、等，可任意组合，换向手柄有两种安装形式，便于不同方向的操
作，该阀采用并联油路，设计有高压压力输出口与其它液压元件相接提供动力
源。经过特殊设计的密封方式，使阀的密封性能**。该阀广泛用于叉车、环卫
车辆、小型装载机等工程机械的液压系统。本公司生产1到4路
ZT-L20 valve is designed by our company， which is medium-nigh pressure 
integrity way direction changed valve， over-flow valve， over load valve，single way 
valve and oil offset valve etc may be installed per different customer's requirements. 
Over-flow valve may adjust the system pressure. over-load valve may combined the 
working pressure of single oil cylinder， single oil valve is to prevent oil returning， 
direction changed valve function have A，O，Y， P etc， it may be combined random. The directional changed level has two 
installing ways for different operation. The valve is used parallel connection oil route It has pressure releasing outlet to connect other 
hydraulic components tc provide power source. The sealing is specially designed with good sealing. The valve is widely used in the 
hydraulic system of forklift environment vehicle and light Loading machines. valves combination ,1-6 .
