机能符号 Symbol 平衡阀(带外接口) Counterbalance Valve (Vented) 技术参数 Specifications ·工 作压 力 Operating Pressure 280BAR ·流 量 Flow 480L/min ·内 泄漏 Internal Leakage 0.3ml/min.max.to 85% of norminal setting ·先 导比 Pliot Ratio 3:1 ·温 度 Temperature -40°C to +120°(-40°F to+250°F) ·插 孔 Cavity T-24A ·流 体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. ·平衡阀的设定值应该至少为负载压力值的1.3倍。 The setting value of the balance valve should be at least 1.3 times of the load pressure value. ·4口的压力将会增加溢流值,增加值为(1+先导比)×压力值 Backpressure at port 4 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure ·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 Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages 产品特性 Features 带 先 导 协 助开启的 带 外接口 型 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 。 因弹簧 腔 通外接 口 ( 口4),口2的 背 压 不 会 影响阀的 设 定值。 此 阀还 被 称 作运
