机能符号 Symbol Pilot Check Valve 技术参数 Specifications ·工 作压 力 Operating Pressure 350BAR ·流 量 Flow 320L/min ·先 导比 Pliot Ratio 1.8:1 ·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-17A ·流 体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. ·名义先导比为1.8:1。这意味着先导压力为1000psi(70bar),可以 抵消1800psi(125bar)的1口压力。不管先导压力衰退或者消失,即 便是非常短暂,阀亦会打开。 Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss. ·2口的压力直接反作用于先导压力。 Pressure at the port 2 area directly opposes pilot pressure. ·在任何情况下,反向流量从2口流向1口都是不可能的。 Reverse flow through the valve from port 2 to port 1 is not possible under any condition. 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
