机能符号 Symbol 液控单向阀 Pilot Check Valve 技术参数 Specifications ·工作压力 Operating Pressure 350BAR ·流量 Flow 120L/min ·先导比 Pliot Ratio 3:1 ·内泄漏 Internal Leakage 0.07ml/min.max.at operating pressure ·温度 Temperature -30°C to +120°(-22°F to+250°F) ·插孔 Cavity T-2A ·流体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. ·提供软管爆裂保护功能，防止负载坠落，很好地锁住高压负载 Provides hose break protection, prevents loads from drifting and positively locks pressurized loads. ·非常低的泄漏量。阀座和阀芯经过热处理可以有更长的使用寿命。如果负载由于阀发生了移动，说明阀座处很有可能被污染物损坏了，阀需要被替换。 Extremely low leakage. The seat and poppet are heat treated for long life. If the load drifts due to the valve, the seat has probably been damaged by contamination and the valve should be replaced. ·标准未完全密封的先导油路可以使得困在先导油液中的空气排出油路。 Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit. 产品特性 Features 压力降 PRESSURE DROP psi(bar) 压力-流量性能曲线 Performance Curve Pressure Drop vs.Flow 工作 Operation 此阀为先导液控单向阀。它具有非密封导压，钢质阀座并且为非透气型。它允许液流从阀口（口2）向负载口（口1）自由流动，截止其反向液流。先导口（口3）的压力使阀开启从口1到口2的流道。口3
