德國力士樂雙單向節(jié)流閥有座式和蝶閥兩類。隨著技術(shù)的發(fā)展，調(diào)節(jié)閥的結(jié)構(gòu)型式越來越多，調(diào)節(jié)閥結(jié)構(gòu)型式的選擇主要是根據(jù)工藝參數(shù)（溫度、壓力、流量）、介質(zhì)性質(zhì)（粘度、腐蝕性、毒性、雜質(zhì)狀況）以及調(diào)節(jié)系統(tǒng)的要求（可調(diào)節(jié)比、噪音、泄漏量）綜合考慮來確定。般情況下，應(yīng)*普通單、雙座閥和套筒閥。因?yàn)榇祟愓{(diào)節(jié)閥結(jié)構(gòu)簡單，閥芯形狀易于加工，比較經(jīng)濟(jì)；或根據(jù)具體的特殊要求選擇相應(yīng)結(jié)構(gòu)形式的調(diào)節(jié)閥。結(jié)構(gòu)型式確定以后，調(diào)節(jié)閥的具體規(guī)格關(guān)系到閥的流量特性是否與系統(tǒng)特性相匹配，關(guān)系到系統(tǒng)是否穩(wěn)定性高、經(jīng)濟(jì)性好。調(diào)節(jié)閥的流量特性，是指流體流過調(diào)節(jié)閥的相對(duì)流量與調(diào)節(jié)閥的相對(duì)開度之間的關(guān)系。易推知，相對(duì)流量與相對(duì)開度成正相關(guān)，即閥門通道越小，相對(duì)開度越小，相對(duì)流量越小；
