机能符号 Symbol 先导式溢流阀 Pilot-operated Relief Valves 技术参数 Specifications ·工作压力 Operating Pressure 380BAR ·流量 Flow 113L/min ·内泄漏 Internal Leakage 5ml/min.max.to 80% of norminal setting ·温度 Temperature -40°C to +120°(-40°F to+250°F) ·插孔 Cavity 10-2 ·流体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. 产品特性 Features 压力降 PRESSURE DROP psi(bar) 压力达到阀设定值，阀开始向油箱（口2）溢流，节流以调节压力。此类阀压力调节精度高，压力波动随流量变化小，并且调节平稳，噪声小，响应速度适中。 Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating Valve. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. These Valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast. 压力-流量性能曲线 Performance Curve Pressure Drop vs.Flow ·硬化处理,零件耐久性强。 Hardened,precision ground parts for durability. ·因为滑阀的泄露,不适合使用在负载锁紧应用中。 Not suitable for use
