Auto Unloading Waterjet Spare Parts Electro Hydraulic Relief Valve

Electro-Hydraulic Relief Valve

The safety protection function of “auto unloading” is provided in the water cutting machine. The safety protection device is designed specially for ensuring safety of personnel and equipment in case the pressure rises up suddenly during operation.

A relief valve is installed in the hydraulic system. When the system pressure reaches the preset value, the relief valve unloads automatically; at the same time, there is another system for ensuring the function of auto unloading: when the system pressure reaches or goes over the preset value, the pressure sensor will generate a signal to the pressure indicator which will pass on the signal to the unloading valve, then the unloading valve breaks off and the oil discharges from it.
