The utility model relates to the technical field of hydraulic valve, specifically to an unloading overflow valve. The utility model provides a novel unloading overflow valve composed of a pilot valve, a main valve with a main valve core and a check valve. The utility model is characterized in that the pressure regulating valve core of the pilot valve is in arc form.

Unloading relief valves are primarily used in hydraulic circuits incorporating accumulators where a pressure regulator is required to automatically unload the pump when the pressure reaches the pre-adjusted pressure setting of the valve. When the pressure has dropped to approximately 85% of the valve setting the valve spool closes, thus diverting the

Unloading Relief Valves. These valves are used to operate the pumps with minimum load in accumulator circuits or in high-low pump circuits. In accumulator circuits, when the system pressure reaches to a cut out pressure (adjusted maximum), the valve acts to divert the pump delivery to the reservoir at low pressure, thus the pump is unloaded automatically.

Unloading valves are very similar to pilot operated, balanced relief valves. The only difference is where the pilot pressure comes from. In unloading valves when external pressure is applied to Port X that is greater than the pilot setting, the pilot poppet will crack open, allowing the main poppet to open.
