Z2S型閥是疊加式結(jié)構(gòu)的液控單向閥。即使長時(shí)間的保壓，一個(gè)或兩個(gè)工作油口仍保持無泄漏的密封。由A至A1或由B至B1是自由流通的，而反方向則封閉。如油從B流經(jīng)閥至B1，壓力作用在活塞上?；钊阆蜃筮\(yùn)動(dòng)，將錐閥芯推離其閥座。此時(shí)油便可從A1流向A。為保證錐閥芯正確閉合，當(dāng)控制閥處于中位時(shí)，閥的工作油口與油箱相通。Z2S22-30B疊加式液控單向閥  Z2S22A-30B 疊加式液控單向閥  Z2S22B-30B 疊加式液控單向閥  Z2DB6VC1-40B/100疊加式溢流閥  Z2DB6VC1-40B/200疊加式溢流閥  Z2DB6VC1-40B/315疊加式溢流閥  Z2DB6VD1-40B/100 疊加式溢流閥  Z2DB6VD1-40B/200疊加式溢流閥  Z2DB6VD1-40B/315疊加式溢流閥  Z2DB6VD1-40B/100 疊加式溢流閥  Z2DB6VD1-40B/200疊加式溢流閥  Z2DB6VD1-40B/315疊加式溢流閥  Z2DB10VC-1-40B/100疊加式溢流閥  Z2DB10VC-1-40B/200 疊加式溢流閥  Z2DB10VC-1-40B/315疊加式溢流閥  Z2DB10VD-1-40B/100疊加式溢流閥  Z2DB10VD-1-40B/200 疊加式溢流閥  Z2DB10VD-1-40B/315疊加式溢流閥
