Rexroth節(jié)流閥的性能要求對節(jié)流閥的性能要求是：節(jié)流閥流量調(diào)節(jié)范圍大，流量一壓差變化平滑； ·內(nèi)泄漏量小，若有外泄漏油口，外泄漏量也要??； ·調(diào)節(jié)力矩小，動(dòng)作靈敏。
Rexroth節(jié)流閥（throttle valve）的外形結(jié)構(gòu)與截止閥并無區(qū)別，只是它們啟閉件的形狀有所不同。Rexroth節(jié)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(dá)到調(diào)節(jié)流量和壓力。節(jié)流閥供在壓力降極大的情況下作降低介質(zhì)壓力之用。介質(zhì)在節(jié)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(xiàn)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(jié)流。
