力士樂高頻響比例閥是比例閥中動態響應性能最接近伺服閥的一種產品，雖然頻率和敏感度比不上伺服閥，但是它無零位死區、高精度、高頻響、對油液的清潔度要求比伺服閥低，因此它具有更高的工作可靠性。
采用力士樂高頻響比例閥時應同時采用蓄能器或增設緩沖回路以消除液壓沖擊，因為管路的沖擊也影響著高頻響比例閥的穩定響應。油路長度是否合理、管路壁厚是否合理、管路是否緊固、直接影響到管路的固有頻率，從而影響著比例閥的穩定響應。
一、高頻響比例閥工作原理
下面以某鋼鐵廠煉鐵分廠爐頂料流調節閥液壓控制系統采用的高頻響比例控制為例來說明。這是BOSCHRESROTH公司生產的一種直接作用滑閥式比例閥，驅動是帶位置反饋和放大器的電磁鐵。工作原理如圖所示，高頻響比例電磁鐵驅動閥芯，位移由位置傳感器反饋，由內置電子線路進行閥芯的閉環控制。經計算機運算處理后執行機構動作的電氣信號由放大器放大后，電磁鐵線圈中就有電流通過，在電液轉換器中將電氣信號轉換成液壓信號，使比例閥主閥芯移動。一個帶放大器的系統，比無放大器的系統重復精度要高得多，而精度直接與放大器的增益有關。
二、故障分析
1、閥門反應速度太慢，動態失效，原因可能是閥太臟，節流孔被堵住，不過最好不要自己拆，應該找廠家配合清洗伺服閥。
2、油路通，卻無法靜載啟動即系統無法平衡可能是密封件失效，更換密封件即可。
