CDA4-F15型多路换向阀是参考国外同类*产品，并根据国内工程车辆的实际需要研制而成的新产品。该产品具有功能全、性能佳、结构紧凑、体积小、重量轻等优点，并在保证进口样机性能的前提下，加大了油路通道，使压力损失减小，降低了能耗、减小了系统的发热。
CDA4-F15型多路换向阀为片式结构，用户根据需要可在10连内任意选用，可组成并联、串并联及并联与串并联的组合油路形式，有O、Ox、R、A、B、Y等多种滑阀机能。其中R型机能用于叉车门架前限速，避免由于负载和门架重力作用而产生的超速运动和气穴现象，使前倾动作安全平稳，Ox型机能用于执行机构中属具的工作，它能有效的保证属具动作平稳可靠。各种机能具有良好的微动特性，各工作油口可安装过载阀，其压力按用户要求调定。
CDA4-F15型多路换向阀进油阀体上设有控制主系统压力的主安全阀和控制转向系统压力的转向安全阀，其结构紧凑，启闭性能好，噪声小，进油阀体内可带一稳流装置向转向系统提供稳定流量，保证转向系统的正常工作，从而实现单泵同时供油给转向系统和工作系统。该产品适用于3吨以下的叉车、轻中型装载机及其它工程，矿山机械的液压系统中。它不但能实现多个执行机构的集中控制，并可带单路稳流分流阀向主机转向系统提供稳定地流量，使转向性能可靠，理想的替代了进口元件。
The CDA4-F15 multiple directional control valve development with reference to similar foreign products ,and According to actual needs of Domestic engineering vehicles.The product has the advantage of widely function ,good performance,compact small size,light weight ,and so on ,and to ensure that imports of prototype performance under the premise of increased oil channel,so that the pressure to reduce losses and lower energy consumption,by a small system heating.
The CDA4-F15 multiple directional control valve for the chip structure,users need to be connected within any of 10 joint selected can be composed of parallel ,serial and parallel with the series-parallel combination in the form of oil,O.Ox.R.A.B.Y slide valves and other functions.R-function for which the forklift truck door frame smoothly ,Ox - functioning institutions for the implementation of a work .It can be an effective action to ensure a smooth and reliable.A variety of functions have good characteristics of fretting ,I work in the oil can overload the installation of valves,pressure by the user will be asked for a transfer.
The CDA4-F15 multiple directional control valve has shifted the main safety valve to control of the main system pressure and safety valve to control of the steering system pressure in the body .Its compact structure ,good performance
headstock ,small noise ,filling valve can bring a steady flow device in body provide a stable flow to steering system to guarantee the normal operation of the system.At the same time,in order to achieve single pump oil to the steering system and work system .It applies to the following 3-ton forklift,small excavators ,loaders and other small-scale projects,mining machinery’s hydraulic system. It will not only focus on the realization of control by a number of agencies implementation,and with current shunt single valve to the host steering to provide a stable flow,to make steer reliable,the ideal substitute for imported components.
