导压比3:1 , 标准型 平衡阀
流量: 60 L/min. | 插孔: T-11A
带先导协助开启的平衡阀是用来控制超驰负载。它允许油液从方向阀（口2）到负载口（口1）单向自由流通，同时直动式，先导协助溢流阀功能可以控制从口1到口2的液流。口3的先导协助以先导比率的作用系数降低了溢流功能的有效设定值。此阀还被称作运动控制阀或者越过中心阀。
平衡阀的设定值应该至少为负载压力值的1.3倍。
顺时针旋转调节将会减少设定，降低压力。
完全释压情况下，设定低于200psi（14bar）。
2口的背压将会增加溢流值，增加值为（1+先导比）×压力值
标准设定下，阀的复位压力值高于阀开启值的85%。当设定值小于标准设定值，复位压力值的百分比将相应变小。
此阀在先导级没有主动密封，因此口3和口2将会有3 in³/min@1000 psi (45 ml/min.@70 bar)的泄漏量。这在主从回路以及阀-缸回路的泄漏测试中需要考虑进去。
配置EPDM密封圈的插装阀可用在磷酸酯液压油系统。暴露在石油基液压油或润滑油脂中会损坏密封圈。
Sun的平衡阀可以被安装进执行器内部的安装孔，成为执行器的一部分，进而更加安全地保护回路。
