    力士乐高频响比例阀是比例阀中动态响应性能最接近伺服阀的一种产品，虽然频率和敏感度比不上伺服阀，但是它无零位死区、高精度、高频响、对油液的清洁度要求比伺服阀低，因此它具有更高的工作可靠性。
    采用力士乐高频响比例阀时应同时采用蓄能器或增设缓冲回路以消除液压冲击，因为管路的冲击也影响着高频响比例阀的稳定响应。油路长度是否合理、管路壁厚是否合理、管路是否紧固、直接影响到管路的固有频率，从而影响着比例阀的稳定响应。
    一、高频响比例阀工作原理
    下面以某钢铁厂炼铁分厂炉顶料流调节阀液压控制系统采用的高频响比例控制为例来说明。    这是BOSCHRESROTH公司生产的一种直接作用滑阀式比例阀，驱动是带位置反馈和放大器的电磁铁。工作原理如图所示，高频响比例电磁铁驱动阀芯，位移由位置传感器反馈，由内置电子线路进行阀芯的闭环控制。经计算机运算处理后执行机构动作的电气信号由放大器放大后，电磁铁线圈中就有电流通过，在电液转换器中将电气信号转换成液压信号，使比例阀主阀芯移动。一个带放大器的系统，比无放大器的系统重复精度要高得多，而精度直接与放大器的增益有关。
    二、故障分析
    1、阀门反应速度太慢，动态失效，原因可能是阀太脏，节流孔被堵住，不过最好不要自己拆，应该找厂家配合清洗伺服阀。
    2、油路通，却无法静载启动即系统无法平衡可能是密封件失效，更换密封件即可。
