D634-371C?R24K02MONSS2电液比例阀简称比例阀。普通液压阀只能通过预调的方式对液流的压力、流量进行定值控制。但是当设备机构在工作过程中要求对液压系统的压力、流量参数进行调节或连续控制，例如.要求工作台在工作进给时按慢、快、慢连续变化的速度实现进给，或按一定精度模拟某个最佳控制曲线实现旅力控制.普通液压阀则实现不了。这时可以用电液比例阀对液压系统进行控制。

电液比例阀是一种按输入的电信号连续地、按比例地控制液压系统的液流方向、流量和压力的阀类。它山电-机械比例转换装置和液压控制阀本体两大部分构成.前者将输入的电信号连续地按比例地转换为机械力和位移输出，后者在接受这种机械力和位移之后、按比例连续地输出压力和流量.VT-NE502-1X/V0/0 0811405152 VT-VARAP1-527-20/V0 0811405153 VT-VARAP1-537-20/V0 0811405154 VT-VARAP1-537-20/V0/5/3V 0811405155 VT-VARAP1-527-20/V0/2STV 0811405156 VT-VARAP1-527-20/V0/3/2VAX 0811405157 VT-VACAP-500-20/V0 0811405158 VT-VACAP-500-20/V0/2CH 0811405162 VT-SSPA1-508-20/V0/1 0811405164 VT-SWMA5-5-1X/V0/0 0811405169 VT-SSBD1-500-10/V0/A 0811405170 VT-SSBD2-500-10/V0/A 0811405171 VT-SSBD2-500-10/V0/A-2F 0811405174 LEITDRPLBESTUECKT 0811405531 HM18-1X/210-V-R/V0/0 0811405532 HM18-1X/350-V-R/V0/0 0811405533 HM18-1X/080-V-S/V0/0 0811405534 HM18-1X/200-N-B/V0/0 0811405535 HM18-1X/350-N-B/V0/0 0811405536 HM18-1X/200-N-S/V0/0 0811405537 HM18-1X/100-N-S/V0/0 0811405538 HM18-1X/350-N-S/V0/0 0811405539 HM18-1X/160-C-B/V0/0 0811405540 HM18-1X/210-V-S/V0/0 0811405541

电液比例阀的发展主要有两个途径一是用比例电磁铁取代传统液压阀的手动调节装置或取代普通电磁铁发展起来的;二是由电液伺服阀简化结构、降低精度发展起来的。下面介绍的比例阀均指前者，它是当今比例阀的主流4WRSE10V50-3X/G24K0/A1V

设计中就使比例电磁铁的衔铁在这段行程中工作。因此。改变线圈中的电流，即可在衔铁上得到与其成正比的吸力。用比例电磁铁代替螺旋手柄来调整液压阀，就能使输出乐力或流量与输人电流对应成比例地发生变化。HMP-013/350
