Overflow valve mainly plays the following roles in mining machinery and equipment:
Limit the maximum working pressure of hydraulic system: Overflow valve can prevent the system pressure from exceeding the set value, thus playing the role of safety protection. When the system pressure rises to the limit value that may cause damage, the overflow valve will open to guide excess oil to the low pressure side to prevent the system pressure from rising excessively.
Keep the pressure of the hydraulic system constant: In the throttling regulation system of the quantitative pump, the overflow valve can keep the pump outlet pressure constant. Even if the system pressure fluctuates due to the load change, the overflow valve can adjust the pressure by opening or closing to maintain the system pressure stability.
Overload protection: When the pressure in the system exceeds the rated value of the overflow valve, the overflow valve will start the overflow to prevent the system components from being damaged or leaked due to excessive pressure.
Unloading function: In some cases, the relief valve can be used as an unloading valve to unload the hydraulic pump and system and reduce energy consumption.
Remote pressure regulation: Overflow valve can also be used for remote pressure regulation, allowing the operator to adjust the system pressure from a distance to adapt to different working conditions.
