GVO 723-40-70200 Auxiliary Valve Pressure Relief Valve Hydraulic Safety Valve PC30MR-2 PC35MR-2 PC50MR-2 PC55MR Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC30MR-2 PC35MR-2 PC50MR-2 PC55MR excavators, is a key pressure control valve in the hydraulic system. It regulates hydraulic pressure, releases overload pressure, protects core hydraulic components such as the main valve and hydraulic pump, and ensures stable operation of the entire machine.

This relief valve is precision-machined from high-quality steel and undergoes overall quenching treatment. Equipped with oil-resistant and high-pressure-resistant seals, it boasts excellent sealing performance, impact resistance, and wear resistance. Suitable for the high-pressure hydraulic conditions of excavators, it effectively prevents internal leakage, pressure loss, operational instability, and vibration.

Product Introduction

This overflow valve, designed for PC30MR-2, PC35MR-2, PC50MR-2, and PC55MR tailless small excavators, is a core cartridge-type pressure protection component on the main control distribution valve assembly. It is mainly used to set and limit the maximum working pressure of the entire hydraulic system of the machine, forming a crucial overload protection line for the entire hydraulic circuit. 

The valve body of this overflow valve is forged from high-grade alloy steel as a whole and undergoes complete quenching and tempering treatment. The overall mechanical strength of the valve body is sufficient, and it has excellent resistance to impact and high-pressure oil flushing. It can withstand the hydraulic impact brought by the high-intensity and high-frequency operations of the tailless small excavator for a long time. The valve core and valve seat are processed by high-precision matching grinding technology, forming a micron-level precise clearance. This ensures that the valve component responds sensitively and quickly during overload relief conditions, and can achieve a tight closure during normal operation of the equipment. This minimizes internal leakage of the valve component and avoids unnecessary power loss caused by abnormal overflow.
