机能符号 Symbol 减压/溢流阀 Pressure Reducing/Relieving Valve 技术参数 Specifications ·工作压力 Operating Pressure 350BAR ·流量 Flow 40L/min ·导压流量 Pliot Flow 0.11 - 0.16L/min ·温度 Temperature -40°C to +120°(-40°F to+250°F) ·插孔 Cavity T-11A ·流体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. 压力-流量性能曲线 Performance Curve Pressure Drop vs.Flow No Load Pressure Drop with Valve Full Open 工作 Operation 先导控制式，溢流型减压阀将进口（口2）高压主油路压力调节减至口1 所需的减压压力，同时具备从口1到油箱（口3）的全流量溢流功能。 Pilot-operated, pressure reducing/relieving valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pre 压力降 PRESSURE DROP psi(bar) ·从减压压力口（口1）到进口（口2）的反向液流可能导致主阀芯关闭。如果油路中需要反向自由流，可以考虑在油路中加入单向阀 Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit ·先导式操作阀具有非常
