GVO AT168765 Pressure Relief Valve Control Valve Hydraulic Safety Valve E300D E310D E315D Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with E300D E310D E315D  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 direct-action threaded cartridge relief valve has a compact structure, strong resistance to oil contamination, and a wide pressure regulating range. In harsh construction environments, it provides stable and reliable overpressure protection for the entire hydraulic system of the machine.

When an excavator is in excavation, heavy-load, or rotation operations, the hydraulic circuit will frequently experience instantaneous high-pressure impacts. If there is no reliable relief protection, problems such as valve component wear, oil pipe rupture, and pump body damage are likely to occur. This relief valve can effectively mitigate the risks of such working conditions. The external threads of the valve body are precisely machined, and the assembly has a high degree of fit. It is equipped with an O-ring to achieve reliable external sealing and prevent oil leakage at the installation position. The internal springs have undergone durability fatigue tests and are not prone to spring attenuation and failure after long-term repeated opening and closing. The tail pressure regulating structure supports on-site pressure adjustment and can match the system pressure parameters of different models. It can be used for new machine matching and also for fault repair and replacement of old machines, effectively improving phenomena such as high temperature, pressure, and slow operation of the equipment system.
