本电磁溢流阀由溢流阀和电磁换向阀组成。电磁换向阀直接安装在溢流阀上，并与溢流阀遥控口连通，系统压力可以由电磁线圈的电力信号遥控，令连接遥控溢流阀可实现两级或三级的压力控制。

These valves are a combination of relief valve and solenoid valve. Piping between the two valves is eliminated as the solenoid valve is directly mounted on the relief valve andconnected with the relief valve vent. Pump pressure may be unloaded remtely by an electrical signal to the solenoid, or by connecting the pilot relief valve to the solenoid valve ports.
