GVO 87426717 Pressure Relief Valve Control Valve Hydraulic Safety Valve U80C B110C U80B U80 B90B Excavator Mechanical Parts

Product Description

The GVO excavator relief valve, compatible with U80C B110C U80B U80 B90B 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 can serve as the main circuit's overflow protection, and can also be used for pressure limitation of branch circuits. It is specifically designed to address common faults such as insufficient hydraulic pressure, vehicle stalling, weak operation, and abnormal noise from oil circuit impact in excavators. Each product undergoes hydraulic bench pressure testing and calibration before leaving the factory. The opening pressure, reseating performance, and internal leakage indicators are all strictly controlled.

During heavy-load operations of construction machinery, the hydraulic circuits often experience instantaneous high-pressure surges, which can easily cause valve damage, oil pipe rupture, and other faults. This overflow valve can effectively mitigate such risks. The external thread processing of the valve body is of high precision, and the assembly is tight. The O-ring is used to achieve good external sealing, preventing leakage at the installation position. The internal springs have undergone fatigue durability tests, and they are not prone to spring attenuation and failure during repeated opening and closing operations. The tail pressure regulating structure supports adjusting the system pressure as needed, meeting the requirements of different equipment's oil circuit parameters. Whether it is for new machine matching or for repairing and replacing faulty equipment, it can stably output performance, improving problems such as high temperature, pressure憋, and weak operation of the equipment system.
