Pilot-operated relief valve MRQEB series-1

机能符号 Symbol 先导式溢流阀 (自动跳合) Pilot-operated Relief Valve (Kick-down) 技术参数 Specifications ·工 作压 力 Operating Pressure 350BAR ·流 量 Flow 95L/min ·内 泄漏 Internal Leakage 30ml/min.max.to 80% of norminal setting ·温 度 Temperature -40°C to +120°(-40°F to+250°F) ·插 孔 Cavity T-10A ·流 体 Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt. ·主级的阻尼孔被150微米的不锈钢滤网保护。 Main stage orifice is protected by a 150-micron 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. ·如应用在系统的驱动端侧,通过阀的液流必须停止,阀才能回座。 如果应用在一个系统的泵端侧,泵必须关闭,阀才能回座。 Intended for use on the actuator side of the system as flow through the valve must cease for the valve to reset. If used on the pump side of a system, pump flow must be shut off for the valve to reset. 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 自 动 跳 合 溢流阀与 电 路中的 断 路器 功 能 类似。 当 进口( 口1)压力 超 过 阀 的 设 定 值,此类 阀 会完全 打 开并 且 保 持全开 状 态,液 流 从 口1到油箱 ( 口2)自 由 流通。 只 要口1压力超 过 口2压力, 阀 就会一 直 保 持 打 开 状态。 要 想 重 新 设定此类 阀 ,口1到口2的液 流 必须停 止 而 且口2的压 力 必须
