DF系列整体式多路换向阀
DF SERIES MONOLITHIC MULTIPLE DIRECTIONAL CONTROL VALVES
DF25、32系列整体式多路换向阀是我公司在国内外同类产品基础上优化设计推出的特色新产品。该产品阀体哦采用高强度球墨铸铁;油路为串并联形式;操作方式有手动操纵、液控操纵。定位复位方式为弹簧复位与钢球定位两种形式。各工作油口可设置可调节叠加式结构的过载阀与补油阀。其位置可根据用户要求灵活组合。各油口均为法兰连接且有多个布置位置供用户选择。该阀具有压力高、流量大、压力损失小、微动特性好、附加阀齐全、操纵力小、结构紧凑、工作可靠、维修方便等特点。适用于装载机、推土机、压路机等大中型工程机械的液压系统中,实现多个执行机构的集中控制。
The DF25、32 monolithic multiple directional control valves are our company both at home and abroad on the basis of similar products to optimize the design characteristics of the introduction of new products .The used of high-strength ductile iron valve body;for oil in the form of series and parallel;there are ways to manipulate manual manipulation ,manipulation of fluid control .Positioning mode reset for spring ball and position in two forms.I work in the oil can be set up adjustable-stack structure of the set-off valve and fill valve oil.Its location can be flexible combination of user requirements.The flange connecting the oil port and there are a number of arrangements for the location of the user to choose.The valve has a high-pressure,flow,pressure loss in small,micro-features,and complete additional valve ,the power to manipulate small,compact,reliable,convenient maintenance and so on .Apply to the loaders,bulldozers,road roller,and other large and medium-sized construction machinery hydraulic system,to achieve the implementation of a number of institutions of centralized control.
