4WEH16E7X/6EG24N9ETK4順序閥只有開啟和切斷兩種狀態(tài),，不象溢流閥那樣有自動(dòng)穩(wěn)壓調(diào)節(jié)作用;
　　(2)順序閥進(jìn)出油口都是壓力油路，所以它的泄油口必須單獨(dú)引回油箱,，而溢流閥則和出口合并一同流回油箱。
　　(3)順序閥的進(jìn),、出油口一經(jīng)接通,，油液通過該閥的壓力損失較小，而溢流閥處于溢流狀態(tài)時(shí),，壓力損失一般較大,。4WEH16E7X/6SG24N9ETK4/

　　四,、壓力繼電器
　　壓力繼電器是利用液體壓力信號(hào)控制電氣觸點(diǎn)通斷的液壓電氣轉(zhuǎn)換元件，當(dāng)油液的壓力達(dá)到其設(shè)定壓力時(shí),，壓力繼電器發(fā)出電信號(hào),，以控制電氣元件動(dòng)作，實(shí)現(xiàn)執(zhí)行元件的順序動(dòng)作或系統(tǒng)的安全保護(hù)和動(dòng)作互鎖,。0811404664 4WRLE10V85M-3X/G24K0/B5M
