4WRA6V30-22/G24N9K4/V-589伺服比例阀

4WRA6V30-22/G24N9K4/V-589伺服比例阀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4wreem6e1-32-20/g24k34/b6v R901037662

，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

，*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。DRE10-5X/200YG24K4M
