CDA4-F15多路換向閥
CDA4-F15 MULTIPLE DIRECTIONAL CONTROL VALVES
CDA4-F15型多路換向閥是參考國外同類產品，并根據國內工程車輛的實際需要研制而成的新產品。該產品具有功能全、性能佳、結構緊湊、體積小、重量輕等優點，并在保證進口樣機性能的前提下，加大了油路通道，使壓力損失減小，降低了能耗、減小了系統的發熱。
CDA4-F15型多路換向閥為片式結構，用戶根據需要可在10連內任意選用，可組成并聯、串并聯及并聯與串并聯的組合油路形式，有O、Ox、R、A、B、Y等多種滑閥機能。其中R型機能用于叉車門架前限速，避免由于負載和門架重力作用而產生的超速運動和氣穴現象，使前傾動作安全平穩，Ox型機能用于執行機構中屬具的工作，它能有效的保證屬具動作平穩可靠。各種機能具有良好的微動特性，各工作油口可安裝過載閥，其壓力按用戶要求調定。
CDA4-F15型多路換向閥進油閥體上設有控制主系統壓力的主安全閥和控制轉向系統壓力的轉向安全閥，其結構緊湊，啟閉性能好，噪聲小，進油閥體內可帶一穩流裝置向轉向系統提供穩定流量，保證轉向系統的正常工作，從而實現單泵同時供油給轉向系統和工作系統。該產品適用于3噸以下的叉車、輕中型裝載機及其它工程，礦山機械的液壓系統中。它不但能實現多個執行機構的集中控制，并可帶單路穩流分流閥向主機轉向系統提供穩定地流量，使轉向性能可靠，理想的替代了進口元件。
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.
