GVO 723-40-50100 Main Pressure Relief Valve Hydraulic Safety Valve PC200-6 PC210-6 PC220-6 PC230-6 Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with PC200-6 PC210-6 PC220-6 PC230-6 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 main relief valve is compatible with the main control distribution valves of PC200-6, PC210-6, PC220-6, and PC230-6 excavators. It serves as the core component for controlling the main pressure of the entire hydraulic system, commonly known as the main gun in the industry. It is responsible for limiting the pressure of the entire hydraulic main circuit and providing overload protection. The relief valve directly controls the digging force, rotation torque, and walking power output of the entire machine. The working state of the valve directly affects the smoothness of the machine's compound actions. Once the relief valve is worn, the spring becomes fatigued, or there is internal leakage, the equipment will experience a series of faults such as insufficient digging force, heavy-load pressure build-up, decreased pressure during hot operation, and jittery movements. This is a highly precise hydraulic component with a high frequency of maintenance and replacement for the -6 series models' distribution valves.

The valve body is forged from high-quality alloy steel as a single piece, and undergoes multiple quenching and tempering heat treatment processes. The overall structure has high strength and can withstand continuous high-pressure impacts and alternating loads during the excavator's operation. The valve core is processed using a high-precision mirror surface grinding method, with strict control over the clearance between the valve core and the valve sleeve. It is paired with high-elasticity anti-fatigue springs and high-pressure-resistant anti-aging sealing components to effectively resist wear and scratches caused by impurities in the hydraulic oil. In heavy-load working conditions such as earthwork construction and gravel operations, the valve core responds quickly and precisely when opening, releasing pressure, and resetting, with stable pressure output. This effectively suppresses common problems such as internal leakage, valve jamming, and pressure drift, ensuring the stable operation of the entire hydraulic system.
