ZDSF（H）型直行程分流、合流電動調(diào)節(jié)閥，由三通分流，合流閥門配用PS系列直行程電動執(zhí)行機構(gòu)組成。電動執(zhí)行機構(gòu)內(nèi)有伺服系統(tǒng)，無需另配伺服放大器，有輸入控制信號（4－20mADC或1－5VDC）及單相電源即可控制運轉(zhuǎn)，實現(xiàn)對壓力、流量、溫度、液位等參數(shù)的調(diào)節(jié)。電動精小型三通調(diào)節(jié)閥是專門針對三通控制研制的專用調(diào)節(jié)閥，具有調(diào)節(jié)精度高，動作穩(wěn)定可靠等優(yōu)點。合流閥主要用于將兩種流體混合成第三種流體；分流型主要用于將一股流體分成兩股流體。該產(chǎn)品可替代兩臺互為開關(guān)的單、雙座調(diào)節(jié)閥，用于液體、氣體、蒸汽等介質(zhì)的調(diào)節(jié)與控制。
