SMC精密調(diào)壓閥出廠時設(shè)置閥芯位置為全開，當(dāng)有壓流體介質(zhì)流經(jīng)閥門后，閥后管道內(nèi)壓力慢慢升高到預(yù)置調(diào)節(jié)壓力值的同時，介質(zhì)通過預(yù)先安裝在精密調(diào)壓閥膜片或活塞執(zhí)行機構(gòu)和閥后管道之間連接的引壓銅管（或不銹鋼管）實現(xiàn)引壓作用，使調(diào)壓閥執(zhí)行機構(gòu)內(nèi)產(chǎn)生相應(yīng)的壓力，然后通過和執(zhí)行機構(gòu)連接的閥桿產(chǎn)生推力來克服閥桿填料摩擦力和調(diào)壓閥彈簧預(yù)緊力從而使閥芯產(chǎn)生上下直線運動來控制閥芯的開度以調(diào)節(jié)改變介質(zhì)壓差和流量，實現(xiàn)調(diào)壓的目的。當(dāng)閥后介質(zhì)壓力值升高超過設(shè)定調(diào)節(jié)壓力時，執(zhí)行機構(gòu)產(chǎn)生的下推力增大，閥芯向下直線位移使閥門開度減小，隨之閥后介質(zhì)壓力相應(yīng)下降；當(dāng)閥后介質(zhì)壓力值減小到低于調(diào)壓閥設(shè)定壓力時，執(zhí)行機構(gòu)產(chǎn)生的下推力減小，閥芯依靠調(diào)壓閥彈簧預(yù)緊力產(chǎn)生的向上推力，克服執(zhí)行機構(gòu)產(chǎn)生的下推力和閥桿摩擦力后，使閥芯向上運動，閥門開度增大改變介質(zhì)壓差和流量，使閥后介質(zhì)壓力又向上回升，趨于接近調(diào)壓閥設(shè)定壓力值。這樣周而復(fù)始，循環(huán)動態(tài)調(diào)節(jié)，使調(diào)壓閥終實現(xiàn)調(diào)壓穩(wěn)壓作用。 

 

SMC精密調(diào)壓閥組以一臺（單路）或二臺（雙路）自力式壓力調(diào)節(jié)閥為主體，配以安全閥、手動球閥、過濾器、旁路手動閥、壓力表等組成一套完善的調(diào)壓系統(tǒng)。它不需要任何外加能源，利用被調(diào)介質(zhì)自身能量而實現(xiàn)自動調(diào)節(jié)的調(diào)壓閥組。該系統(tǒng)大特點，能在無電、無氣的場所工作。既節(jié)約了能源，而壓力設(shè)定值在運行中可隨意調(diào)整。因而它廣泛應(yīng)用于石油、深冷、電子、化工、電力、冶金、天然氣、食品等各種燃氣門站、區(qū)域調(diào)壓和氣體、液體的調(diào)壓場合      ASD430FG-02-10SSMC調(diào)壓閥ASD430FG-02-10S
