萬(wàn)福樂(lè)比例節(jié)流閥MQPPM22-350-G12/MEA1 節(jié)流閥(Choke valve)的外形結(jié)構(gòu)與截止閥并無(wú)區(qū)別，只是它們啟閉件的形狀有所不同。
節(jié)流閥的啟閉件大多為圓錐流線型，通過(guò)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*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）并制成頂jian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*在小縫隙下節(jié)流。由于節(jié)流閥的流量不僅取決于節(jié)流口面積的大小，還與節(jié)流口前后的壓差有關(guān)，閥的剛度小，
故只適用于執(zhí)行元件負(fù)載變化很小且速度穩(wěn)定性要求不高的場(chǎng)合。

對(duì)于執(zhí)行元件負(fù)載變化大及對(duì)速度穩(wěn)定性要求高的節(jié)流調(diào)速系統(tǒng)
，必須對(duì)節(jié)流閥進(jìn)行壓力補(bǔ)償來(lái)保持節(jié)流閥前后壓差不變，從而達(dá)到流量穩(wěn)定
