由于电磁铁推力的限制，在大于63L/min的液压系统中，一般不再选用直推式的电磁换向阀，而选用通过流量较大的电液换向阀。电液换向阀的原理是：控制油通过电磁先导阀到达电液阀主阀芯的两端（即电液换向阀主阀体两端盖侧），通过电磁先导阀的换向，来实现主阀芯的左右移动，从而开通或切断通往执行元件的油路，使执行元件运行或停止。但在打开或切断油路的瞬间，系统中会产生相当大的冲击，这种冲击会极大影响液压系统中液压元件和密封件的使用寿命。为了减小及至消除由此引起的液压冲击，最简单的办法是在该电液阀下面叠加一个P口节流阀或进油节流式双单向节流阀、出油节流式双单向节流阀，以延长阀芯的换向及复位时间，从而到降低液压冲击的目的。下面就以弹簧复位型、三位四通中封式电液压换向阀为例、

对该三种叠加节流方式作简要说明。

一、叠加一个P口可调节流阀：控制油先通过叠加可调节流阀、到达电磁先导阀的P口，通过电磁先导阀的换向及调整节流阀的开度，来实现主阀芯的换向延时，从而达到降低主油路与执行元件接通时的换向冲击。但先导电磁阀断电时

上置式油箱把液压泵等装置安装在有较好刚度的上盖板上，其结构紧凑、应用最广。此外还可在油箱外壳上铸出散热翅片，加强散热效果，即提高了液压泵的使用寿命。

侧置式油箱是把液压泵等装置安装在油箱旁边，占地面积虽大，但安装与维修都很方便，通常在系统流量和油箱容量较大时采用，尤其是当一个油箱给多台液压泵供油时使用。因侧置式油箱油位高于液压泵吸油口，故具有较好的吸油效果。

下置式油箱是把液压泵置于油箱底下，不仅便于安装和维修，而且液压泵吸入能力大为改善。

、弹簧复位型电液换向阀主阀体两端盖内的液压油会通过先导电磁阀的中位与泄油口接通、主阀芯在复位弹簧的作用下会立即复位，由于主阀芯复位快、亦即切断执行元件油路的速度快、从而引起液压冲击。

由此可见，叠加一个P口可调节流阀，只能实现换向接通延时、不能解决复位切断延时。注：象油缸类的执行元件，油缸前进与后退时通过换向阀的流量是不一致的，油缸无杆腔与有杆腔的面积比越大、流量差距也越大，此时若想较满意的降低执行元件前进与后退时的液压冲击，通过一个可调节流阀，恐怕是难以实现的。
