比例换向阀 Ex d

Description

先导式比例换向阀,在5腔系统中具有4个接口。非常紧凑的设计,具有相应的低重量和高流速。先导阀和主阀的功能以及两个阀的相互作用可以在液压图中找到。随着电磁电流的增加,阀芯行程、阀芯开度和阀的体积流量都会增加。压力密闭封装的防爆电磁线圈可以防止内部爆炸逼出,以及易燃的表面温度。Wandfluh比例压力阀(见寄存器2.3)和Wandfluh比例放大器(见寄存器1.13)可用于控制目的。

Application

这些阀门适用于有爆炸危险的地方,在露天和矿井中使用。先导式阀门适用于需要控制大流量的地方。由于大流量范围和先导实现的驱动刚度,这些阀门适用于所有需要高加速和减速率、高速度和敏感运动过程的应用。它们被用于工业以及移动液压系统中,以实现液压驱动的平稳和控制操作。
