Rexroth节流阀的性能要求对节流阀的性能要求是：节流阀流量调节范围大，流量一压差变化平滑； ·内泄漏量小，若有外泄漏油口，外泄漏量也要小； ·调节力矩小，动作灵敏。
Rexroth节流阀（throttle valve）的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。Rexroth节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降极大的情况下作降低介质压力之用。介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏－即所谓气蚀现象。为了尽量减少气蚀影响，阀瓣采用耐气蚀材料（合金钢制造）并制成*角为140～180的流线型圆锥体，这还能使阀瓣能有较大的开启高度，一般不推荐在小缝隙下节流。
