The setting procedure is; check the setting, remove the pressure, adjust the valve, check the new setting. ·此阀对变动的油液温度和油液污染不敏感。 Valve is relatively insensitive to varying oil temperatures and oil contamination. 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 （ 口2）溢 流 ，节流 以 限制压 力 上升。 此 类阀调 节 平稳、 噪 声小，基 本 为零 泄 漏 ， 抗 油 污能力 强 ， 防 堵 塞 并且响应 速 度快。 Direct-acting relief cartridges are normally closed, pressure-limiting Valve used to protect hydraulic c
