Product Description:

The unloading valve is usually a relief valve with a two-position two-way valve (usually a solenoid valve).Its function is to set the main pressure of the system (oil pump) when it is not unloaded. Valve action conversion) The pressure oil is directly returned to the tank, and the system pressure is 0. The value is used to achieve some loop control and improve the life of the oil pump and reduce power consumption. It belongs to the integrated loop in the loop. The pressure reducing valve is used to adjust the pressure required by the actuator. It is connected in series in the loop and generally cannot be used interchangeably.

Function of unloading valve:

The main function of the unloading overflow valve is to automatically control the unloading or loading of the pump. In view of the function of the unloading relief valve, there is a certain difference between the unloading pressure and the loading pressure. If the difference is too small, the unloading and loading actions of the pump are too frequent; if the difference is too large, the system pressure changes too much.

The difference between the loading pressure and the unloading pressure is an important performance index of the unloading relief valve. Generally, the loading pressure is about 85% of the unloading pressure. Its performance is the same as that of the relief valve.
