平衡閥是在水力工況下，起到動(dòng)態(tài)、靜態(tài)平衡調(diào)節(jié)的閥門(mén)。平衡閥可分為三種類型：靜態(tài)平衡閥、動(dòng)態(tài)平衡閥及壓差無(wú)關(guān)型平衡閥。靜態(tài)平衡 閥亦稱平衡閥、手動(dòng)平衡閥、數(shù)字鎖定平衡閥、雙位調(diào)節(jié)閥等，它是通過(guò)改變閥芯與閥座的間隙（開(kāi)度），調(diào)整閥門(mén)的Kv（閥門(mén)流通能力）來(lái)改變流經(jīng)閥門(mén)的流動(dòng)阻力以達(dá)到調(diào)節(jié)流量的目的，其作用對(duì)象是系統(tǒng)的阻力，消除系統(tǒng)中阻力不平衡的現(xiàn)象，從而能夠?qū)⑿碌乃堪凑赵O(shè)計(jì)計(jì)算的比例平衡分配，各支路同時(shí)按比例增減。靜態(tài)平衡閥在系統(tǒng)中應(yīng)用場(chǎng)合可以在：總管、立管、水平支管以及末端等使用，效果等同于同程管。
動(dòng)態(tài)流量平衡閥亦稱：限流閥、定流量閥、自動(dòng)平衡閥等，它是跟據(jù)系統(tǒng)工況（壓差）變動(dòng)而自動(dòng)變化阻力系數(shù)，在一定的壓差范圍內(nèi)，可以有效地控制通過(guò)的流量保持一個(gè)常值，即當(dāng)閥門(mén)前后的壓差增大時(shí)，通過(guò)閥門(mén)的自動(dòng)關(guān)小的動(dòng)作能夠保持流量不增大，反之，當(dāng)壓差減小時(shí)，閥門(mén)自動(dòng)開(kāi)大，流量仍照保持恒定，但是，當(dāng)壓差小于或大于閥門(mén)的正常工作范圍時(shí)，它畢竟不能提供額外的壓力，此時(shí)閥門(mén)打到全開(kāi)或全關(guān)位置流量仍然比設(shè)定流量低或高不能控制。
內(nèi)部先導(dǎo)式減壓閥當(dāng)減壓閥的輸出壓力較高或通徑較大時(shí)，用調(diào)壓彈簧直接調(diào)壓，則彈簧剛度必然過(guò)大，流量變化時(shí)，輸出壓力波動(dòng)較大，閥的結(jié)構(gòu)尺寸也將增大。為了克服這些缺點(diǎn)，可采用先導(dǎo)式減壓閥。先導(dǎo)式減壓閥的工作原理與直動(dòng)式的基本相同。先導(dǎo)式減壓閥所用的調(diào)壓氣體，是由小型的直動(dòng)式減壓閥供給的。若把小型直動(dòng)式減壓閥裝在閥體內(nèi)部，則稱為內(nèi)部先導(dǎo)式減壓閥；若將小型直動(dòng)式減壓閥裝在主閥體外部，則稱為外部先導(dǎo)式減壓閥。
