Rexroth節流閥的性能要求對節流閥的性能要求是：節流閥流量調節范圍大，流量一壓差變化平滑； ·內泄漏量小，若有外泄漏油口，外泄漏量也要小； ·調節力矩小，動作靈敏。
Rexroth節流閥（throttle valve）的外形結構與截止閥并無區別，只是它們啟閉件的形狀有所不同。Rexroth節流閥的啟閉件大多為圓錐流線型，通過它改變通道截面積而達到調節流量和壓力。節流閥供在壓力降極大的情況下作降低介質壓力之用。介質在節流閥瓣和閥座之間流速很大，以致使這些零件表面很快損壞－即所謂氣蝕現象。為了盡量減少氣蝕影響，閥瓣采用耐氣蝕材料（合金鋼制造）并制成*角為140～180的流線型圓錐體，這還能使閥瓣能有較大的開啟高度，一般不推薦在小縫隙下節流。
