产品简介：

力士乐REXROTH二通插装阀，压力控制功能

LFA..DBU2A

R900947692 LFA25DBU2A2-71/100A025

R900923101 LFA25DBU2A2-71/315A200

R900932664 LFA32DBU2B2-71/315A200

规格 16 … 100

组件系列 6X, 7X

大工作压力 420 bar

规格 16 … 100

组件系列 6X, 7X

用于压力功能的二通插装阀为先导式座阀或滑阀。设计为插装阀的功率单元安装在按照 DIN ISO 7368 进行标准化的接收孔内，且使用控制盖闭合。

用于手动或电动比例压力调节的先导控制阀作为先导阀集成到控制盖内或安装在控制盖上，其安装尺寸符合 DIN 24 340。

通过将插装阀与控制盖组合，可以实现不同的压力功能。

压力溢流功能

用于压力溢流功能的插装阀（型号 LC .DB...）被设计为无面积差的座阀（在油口 B 处无有效面积）。油口 A 处的有效压力经先导油供油节流孔导入到元件的弹簧侧。在先导控制阀上设定的压力下，阀芯由弹簧力进行压力补偿和闭合。

当达到调定压力时，阀芯开启，且油口 A 处的压力将根据压力-流体特性而受到限制。

减压功能

静止位置开启

用于减压功能的插装阀被设计为无面积差的滑阀（在油口 B 处无有效面积）。

作为先导控制阀，应使用具有压力溢流功能的相同盖类型（型号 LFA..DB...）。

油口 A 处的有效压力经先导油供油节流孔引入到阀芯的弹簧侧。在性能限制和先导控制阀设定的压力下，阀芯由弹簧力进行压力补偿并保持在开启位置，以实现从油口 B 到油口 A 的自由流动。

当达到调定压力时，阀芯闭合并且油口 A 处的压力将根据压力-流体特性降低。
