聯(lián)系我時，請告知來自 泵閥商務網(wǎng)DC20、25、32多路換向閥是我公司根據(jù)國內(nèi)外工程機械液壓系統(tǒng)進行優(yōu)化設計的新型多路換向閥。廣泛適用于裝載機、汽車起重機、推土機、壓樁機等工程機械和大噸位叉車、冶金、農(nóng)業(yè)、塑料等機械的液壓系統(tǒng)中，是主機實現(xiàn)進口元件國產(chǎn)化的理想產(chǎn)品。
DC※系列多路換向閥
DC SERIES MULTIPLE DIRECTIONAL CONTROL VALVES
DC20、25、32多路換向閥是我公司根據(jù)國內(nèi)外工程機械液壓系統(tǒng)進行優(yōu)化設計的新型多路換向閥。廣泛適用于裝載機、汽車起重機、推土機、壓樁機等工程機械和大噸位叉車、冶金、農(nóng)業(yè)、塑料等機械的液壓系統(tǒng)中，是主機實現(xiàn)進口元件國產(chǎn)化的理想產(chǎn)品。
該閥為片式結構、體積小、功能齊全、油路形式多、有并聯(lián)、串并聯(lián)油路，可單泵或雙泵供油，多級壓力控制和分、合流回路等，安裝方便，滑閥可在任意一端伸出，滑閥端部有舌狀和叉狀二種結構?；y機能齊全，除國內(nèi)已有的機能外，還增加了G型、R型、W型等特殊機能，zui多可以控制10個工作機構，能廣泛地滿足用戶要求。
The DC20、25、32multiple directional control valves are in accordance with domestic and foreign engineering machinery hydraulic systems to optimize the design of the new multi-valve.Widely applicable to the truck crane,bulldozer,large-middle forklift ,loader,pressure machine,such as construction machinery and metallurgy ,agriculture,
plastics machinery hydraulic system,is the host of imports of components to achieve the ideal of home-made products.
The valves for the chip structure,small size,full-featured,in the form of oil,have a parallel,series-parallel circuit can be single or double pump oil pump,multi-level control and pressure points,such as merging circuit.It is easy to install,slide valve can be arbitrarily extended at one end,the end of the slide valve has forked and tongue structures.It’s sliding valve function fully ,in addition to the existing internal functions,but also an increase of G-type,R-type,W-type and others special functions.It can control up to 10 bodies,extensive able to meet user requirements.
