4WEH16E7X/6EG24N9ETK4順序閥只有開啟和切斷兩種狀態，不象溢流閥那樣有自動穩壓調節作用;
　　(2)順序閥進出油口都是壓力油路，所以它的泄油口必須單獨引回油箱，而溢流閥則和出口合并一同流回油箱。
　　(3)順序閥的進、出油口一經接通，油液通過該閥的壓力損失較小，而溢流閥處于溢流狀態時，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控制電氣觸點通斷的液壓電氣轉換元件，當油液的壓力達到其設定壓力時，壓力繼電器發出電信號，以控制電氣元件動作，實現執行元件的順序動作或系統的安全保護和動作互鎖。0811404664 4WRLE10V85M-3X/G24K0/B5M

　　按結構特點分為柱塞式、彈簧管式和膜片式。主要零件包括柱塞調節螺帽和電氣微動開關。壓力油作用在柱塞下端，液壓力直接與彈簧力比較。當液壓力大于或等于彈簧力時，柱塞向上移壓微動開關觸頭，接通或斷開電氣線路。反之，微動開關觸頭復位。0811404442 4WRLE27Q4-430M-3X/G24TK0/A1M
