該閥組包含兩部分，各由一個(gè)單向閥和反向管路先導(dǎo)控制的一個(gè)溢流閥組成;單向閥部分允許壓力油自由流入油缸V1→C1(V2→C2)，同時(shí)阻止油反向流動(dòng)保持負(fù)載C1→V1(C2→V2);溢流閥部分在先導(dǎo)壓力建立后，可控制執(zhí)行機(jī)構(gòu)的運(yùn)動(dòng)。溢流壓力設(shè)置通常高于1.3倍的最大負(fù)載壓力，但平衡閥的開啟依靠閥的先導(dǎo)比。該閥通過調(diào)節(jié)執(zhí)行器的輸入流量和輸出流量，經(jīng)C1和C2口提供負(fù)載的靜態(tài)和動(dòng)態(tài)控制。

The valve group consists of two parts, each composed of a one-way valve and a reverse pipeline pilot controlled relief valve;The check valve section allows the pressure oil to flow freely into the cylinder V1→C1(V2→C2), while preventing the reverse flow of oil to maintain the load C1→V1 (C2→V2).The relief valve part can control the movement of the actuator after the pilot pressure is established. The overflow pressure setting is usually higher than 1.3 times the maximum load pressure, but the opening of the balance valve depends on the pilot ratio of the valve.The valve provides static and dynamic control of the load via ports C1 and C2 by regulating the input and output flow of the actuator.
