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、R900975411 DB10-3-5X/200V

R900598149 DB10G2-5X/100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。
