该阀组包含两部分，各由一个单向阀和反向管路先导控制的一个溢流阀组成;单向阀部分允许压力油自由流入油缸V1→C1(V2→C2)，同时阻止油反向流动保持负载C1→V1(C2→V2);溢流阀部分在先导压力建立后，可控制执行机构的运动。溢流压力设置通常高于1.3倍的最大负载压力，但平衡阀的开启依靠阀的先导比。该阀通过调节执行器的输入流量和输出流量，经C1和C2口提供负载的静态和动态控制。

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.
