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 350BAR ·流量 Flow 45L/min ·额定响应时间 Response Time - Typical 10ms ·内泄漏 Internal Leakage 30ml/min.max.at 70bar ·温度 Temperature -40°C to +120°(-40°F to+250°F) ·插孔 Cavity T-162A ·流体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. 产品特性 Features ·主级的阻尼孔被不锈钢滤网保护。 Main stage orifice is protected by a stainless steel screen. ·油箱口（口2）处的背压直接以1:1的比例增加到阀的设定值上。 Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio. ·可在口2接受最大压力；适合应用在交叉端口的溢流油路中。如果应用在交叉端口的溢流油路中，请考虑滑阀泄漏。 Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage. 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-pist
