借助供电设备的 9 V 调节电压，可直接或通过外部控制值电位计将控制值电压施加到控制值输入 1。对于该输入，以下内容有效： 9 V ? 100 % 1）控制值输入 2 是差动输入（0 至 10 V）。借助 DIL 开关 2），可将其配置为电流输入（4 至 20 mA 或 0 至 20 mA）。如果控制值是由具有不同参考电位的外部电子元件（例如，通过 PLC）进行前馈，则必须使用此输入。施加或取消控制值电压时，必须注意将两个信号电缆与输入断开或与之连接。

传递控制值前，将对两个控制值累加，然后供给可通过前面板访问的电位计，该电位计用作衰减器并限制大的控制值。

下游斜坡函数发生器根据阶跃式输入信号产生斜坡状输出信号。借助两个电位计，可分别针对"上"斜坡和"下"斜坡调整该信号的时间常量。****的斜坡时间指的是 100 % 的控制值阶跃变化，视 DIL 开关 2）的设置而定，该时间可能是约 1 s或 5 s。如果将小于 100 % 的控制值阶跃变化提供给斜坡函数发生器的输入或衰减器  有效时，斜坡时间将相应缩短。

以下内容对于 VT-VSPA1-1 类型有效：借助外部触点"斜坡上/下关闭"，可将上斜坡时间和下斜坡时间分别设置为各自的小值（约 30 ms）。

以下内容对于 VT-VSPA1K-1 类型有效：借助外部触点"斜坡关闭"，可将上斜坡时间和下斜坡时间共同设置为各自的小值（约 30 ms）。

电液比例阀是采用了比例控制技术,介于开关型液压阀和电液伺服阀之间的-种液压元件,在工业生产中获得了广泛的应用,输入的电信号有模拟式和数字式两大类,可以用于控制位置(转角)、速度(转速)、加速度(角加速度)、压力(压差)、力(力矩)等参数。电液比例阀等元件可以组成如下三类控制回路和系统

(1)电液比例压力控制回路和系统。例如:用于带钢热连轧机卷取机液压辅助系统的电液比例压力控制回路,用于板带轧机辊缝控制的液压推上系统电液比例压力控制回路,用于带材卷取设备恒张力的闭环电液比例压力控制回路;

(2)电液比例流量控制回路和系统。例如:用于带钢热连轧机精轧机平衡液压系统的电液比例压力控制回路,用于机床微进给的电液比例控制回路,用于旋压机折板机同步的电液比例控制回路,用于电梯的电液比例控制回路;

(3)电液比例多参数控制回路和系统。例如:用于带钢热连轧机精轧换辊液压系统的电液比例压力控制回路,用于液压缸垂直配置而采用wI型阀芯的比例控制回路,用于热轧钢卷步进链式运输机的速度、加减速度控制回路。

 

电液比例阀是阀内比例电磁铁输入电压信号产生相应动作，使工作阀阀芯产生位移，阀口尺寸发生改变并以此完成与输入电压成比例压力、流量输出元件。阀芯位移也可以以机械、液压或电形式进行反馈。电液比例阀具有形式种类多样、容易组成使用电气及计算机控制各种电液系统、控制精度高、安装使用灵活以及抗污染能力强等多方面优点，应用领域日益拓宽。近年研发生产插装式比例阀和比例多路阀充分考虑到工程机械使用特点，具有先导控制、负载传感和压力补偿等功能。它出现对移动式液压机械整体技术水平提升具有重要意义。特别是电控先导操作、无线遥控和有线遥控操作等方面展现了其良好应用前景。
