LRPGE( 导压操作，快速响应型) 先导式溢流阀 工作OPERATION The valves are normally closed, pressure-limiting valves used to protect hydraulics 说明DESCRIPTION components from pressure transients. Fast opening and closing is gained at the A cartridge-style fast-acting expense of smoothness. W hen the pressure at the inlet (port ①） reaches the valve balanced piston relief valve setting，the valve starts to open to tank (port ②), throttling flow to limit the pressure 快速响应型，先导滑阀式溢流阀 rise. These valves have low pressure rise vs. flow and are very fast. Back pressure on the tank port ② is directly additive to the valve setting at a 1:1ratio. 快速响应先导式滑阀型溢流阀用于保护系统的压力瞬时过载，快速启闭时仍能保持系 统平稳性。当①口压力超过阀的设定时，①口到②口溢流过载，限制系统压力升高， 该阀对压力反应灵敏。 ②口背压会按1:1 叠加到阀的设定压力上。 技术参数SPECIFICATIONS 最大工作压力(Max.Operating Pressure): 350bar 流量(Capacity): 200 L/min. 内泄漏(Internal Leakage): 50 cc/min. at 70 bar SYMBOL Factory pressure setting established at 4gpm(15L/min) 工厂的设定是指当溢流阀开启时的压力 响应时间(Response Time- Typical): 2 ms 弹簧调压范围(Standard Spring Ranges): A 7 to 210 bar, preset预设定:70bar B 3.5 to 105 bar, preset预设定
