VT-VRPA1-537-10/V0/QV-RT

VT-VRPA1-537-10/V0/QV-RT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）T6D-038-2R00-C1

，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，*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3DREPE6B-2X-25EG24N9K31/F1M-00
