GVO 723-18-16701 7231816701 Auxiliary Valve Pressure Relief Valve Hydraulic Safety Valve PC50 PC50MR-2 PC50UU-2 Excavator Parts

Product Description

The GVO excavator relief valve, compatible with PC50 PC50MR-2 PC50UU-2  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

The relief valves of the PC50, PC50MR-2, and PC50UU-2 compact excavators are integral plug-in pressure protection valves within the distribution valve assembly. They play a crucial role in limiting the maximum working pressure of the entire hydraulic system of the machine, establishing a solid and reliable overload protection barrier for the entire hydraulic circuit.

The valve body of the relief valve is forged from high-strength alloy steel as a whole and undergoes a complete quenching and tempering hardening process. The overall structural strength of the valve body is sufficient, and it has excellent resistance to impact and high-pressure oil erosion. It can withstand the hydraulic impact erosion caused by the frequent operation of the compact excavator for a long time.The valve core and valve seat are processed by a high-precision matching grinding method, achieving a precise clearance of micrometer level. This ensures that the valve component responds sensitively and quickly during overload relief conditions, while maintaining a tight closure during normal operation of the equipment. This minimizes the internal leakage of the valve component and avoids unnecessary power loss due to abnormal overflow.
