派克BD系列伺服阀结构比较复杂，造价高，对油的质量和清洁度要求高。新型的伺服阀正试图克服这些缺点，例如利用电致伸缩元件的伺服阀，使结构大为简化。另一个方向是研制特殊的工作油（如电气粘性油）。这种工作油能在电磁的作用下改变粘性系数。利用这一性质就可通过电信号直接控制油流。Parker派克BD系列伺服阀在运动控制应用中在对位置、速度和力的控制中提供高分辨率。优点：牢固可靠*工作；降低了的污染敏感度；线性流量增益特性。

  Parker伺服阀，BD15JALND20，原装Parker伺服阀 派克BD系列伺服阀主要用在电气液压伺服系统中作为执行元件（见液压伺服系统）。在伺服系统中，液压执行机构同电气及气动执行机构相比，具有快速性好、单位重量输出功率大、传动平稳、抗干扰能力强等特点。另一方面，在伺服系统中传递信号和校正特性时多用电气元件。因此，现代高性能的伺服系统也都采用电液方式，伺服阀就是这种系统的必需元件。
